What is the Divisibility Rule of 6?
A whole number is said to be divisible past 6 if it fulfills the 2 atmospheric condition given below.
- The whole number has to exist divisible by 2. A number is divisible by ii if the unit identify digit of the number is even, i.eastward 0, 2, 4, half dozen, and 8.
- The whole number has to be divisible by 3. A number is divisible by 3 if the sum of all digits of the number is a multiple of 3 or the sum is exactly divisible past 3.
Both the conditions should apply to the number while doing the divisibility test of half dozen. If a number does not fulfill whatever one of the given conditions or both then we can say that a number is not divisible by 6. In other words, nosotros can say that all the fifty-fifty numbers that come up in the multiplication tabular array of three are divisible by 6.
Let'southward empathize the divisibility rule of 6 with the aid of examples.
a) Applying divisibility test of 6 on the number 9156
Condition one: Number has to be divisible by 2 ⇒ 9156 ends with an fifty-fifty number (half-dozen). It is divisible by 2 [9156 ÷ ii = 4578].
Condition two: Number has to be divisible past 3. The sum of the digits of the number 9156 is 21 (9 + one + five + half dozen = 21). The sum 21 is divisible by iii. The number 9156 is divisible past iii.
Thus, 9156 is divisible by both two and 3. Therefore, it is divisible by 6.
b) Applying divisibility rule of six on the number 825.
Condition 1: Number has to be divisible by two ⇒ 825 ends with an odd number (5). Information technology is Not divisible by 2.
Condition two: Number has to be divisible by iii. The sum of the digits of the number 825 is xv (8+ 2 + 5 = fifteen). The sum xv is divisible past 3. The number 825 is divisible by 3 (825 ÷ 3 = 275).
We can see that 825 is NOT divisible past two and it is divisible by three. Since the number is not meeting i condition, therefore, 825 is NOT divisible by 6.
Divisibility Dominion of 6 for Large Numbers
The divisibility rule of 6 is the same for all numbers whether information technology is a smaller number or a large number. A large number is divisible by 6 if it is divisible by the numbers 2 and iii both. The large number should satisfy both the weather condition of the divisibility test of 6.
Follow the steps to bank check if a large number is divisible past six or not.
- Step 1: Check the unit place digit of the number. If information technology is even, it is divisible by 2 and if it is odd, information technology is NOT divisible by 2.
- Pace 2: Check the sum of all digits of the number. If the sum is divisible by 3 then the number is also divisible by 3.
- Step 3: If footstep ane and pace 2 say that the large number is divisible by ii and three both and then the big number is said to exist divisible past half dozen.
For example, 145962
- Step i: The number is even, and then information technology is divisible by ii.
- Step two: The sum of all digits is 1+four+5+nine+6+2 = 27, yep the sum 27 is divisible past 3 which means 145962 is also divisible by 3. Annotation that the sum of the digits of the number 27 is 2 + 7 = 9 is likewise divisible by 3. Nosotros can repeat this procedure to get the sum closer to three.
- Step 3: The number 145962 is divisible by two and 3 both. Therefore, the number 145962 is divisible by vi.
Divisibility Dominion of 6 and 7
The divisibility rules of 6 and 7 are completely dissimilar. The divisibility rule of vi states that the number should divisible past 2 and three both, if the number is divisible by ii and 3 both, the number said to be divisible by 6, whereas the divisibility dominion for 7 states that for a number to be divisible by vii, multiply the ones place digit of the number by 2, and decrease it with the residuum of the number to its left leaving the digit at the unit of measurement place. If the result is either 0 or a multiple of 7, then the number is divisible by seven.
Divisibility Examination of 6 and 9
Both the divisibility rules of 6 and ix are different from each other. In the divisibility rule of 6, we check whether the number is divisible past ii and iii or not, while in the divisibility test of 9, nosotros calculate the sum of all the digits of the number. If the sum of the digits is a number divisible past 9, and so the given number is besides divisible by 9. Let usa have an example to understand information technology better. To find out whether 450 is divisible by half-dozen and 9, we showtime check its divisibility past ii and 3. The unit place digit of 450 is 0, and then it is divisible by 2, and the sum of the digits is 4+5+0= 9, which is divisible past 3. So, 450 is divisible by 6. Now, every bit nosotros have already calculated that the sum of the digits of 450 is nine, which is divisible by nine. Hence, 450 is divisible past both 6 and 9.

FAQs on Divisibility Rule of 6
What is the Divisibility Dominion of half dozen?
The divisibility rule of 6 says that if a number is divisible by two and 3 both, then the number is also divisible past half dozen. For example, 78 is an even number and then, it is divisible by 2. The sum of 78 is fifteen (7+8=15) and xv is divisible by 3. Therefore, without doing partitioning we can say that the number 78 is divisible by six (78 ÷ vi = 13) as it is divisible by 2 and 3 both.
Using the Divisibility Dominion of vi, Check if 225 is Divisible by six?
Kickoff, nosotros have to bank check that the number 225 is even or odd. As it is odd that ways information technology is non divisible by 2. Since the number is not divisible by 2, and then the number cannot be divisible past half-dozen, because the divisibility rule of half dozen states that the number should divisible by 2 and three both to make it divisible by 6. So, 225 is not divisible by half dozen.
What is the Divisibility Rule of 6 and three?
The divisibility rule of 6 states that the number is exactly divided by number 6 but if it is exactly divided by 2 and 3 both. On the other hand, the divisibility rule of iii states that if the sum of all digits of a number is divisible by 3 or multiple of 3 then the number is divisible by iii. We use this condition (divisibility rule of 3) in the divisibility examination of half-dozen to check whether a number is divisible by 3 or non, and then it is very important to larn the divisibility rule of 3 before learning the divisibility dominion of six.
How do you know if a Big Number is Divisible by 6?
If a big number is divisible by 2 and 3 both and so it is also divisible by 6. For this, we demand to bank check whether the unit place digit of the number is even or odd. If it is even then it is divisible past 2. After that, we need to do the sum of all digits and if the sum is divisible by 3 then the number is also divisible by iii. If both the weather condition satisfied by the number and so without doing partition nosotros can say that the number is divisible by half-dozen.
Using the Divisibility Rule of vi, Check if 288 is Divisible past 6?
According to the divisibility rule of 6, the number 288 should be divisible past two and 3 both. If information technology is not, then the number is not divisible past half dozen. Every bit 288 is an even number information technology is divisible by 2. The sum of digits is 2+8+8 = 18 and 18 is divisible by 3, thus 288 is divisible past 3. And then, yes, 288 is divisible by vi because information technology is divisible by 2 and iii both.
