Best Answer

To be divisible by 6, the number must be divisible by both 2 and 3:

To be divisible by 2 the last digit must be even, ie one of {0, 2, 4, 6, 8};

To be divisible by 3, sum the digits of the number and if this sum is divisible by 3, then the original number is divisible by 3.

As the test can be repeated on the sum, repeat the summing until a single digit remains; only if this number is one of {3, 6, 9} is the original number divisible by 3.

If the number is not divisible by 2 or 3 (or both) then the number is not divisible by 6.

examples:

- 126

1 + 2 + 6 = 9 which is divisible by 3, so it is divisible by 3

â†’ 126 is divisible by both 2 and 3, so it is divisible by 6

- 124

1 + 2 + 4 = 7 which is not divisible by 3, so it is not divisible by 3

â†’ 126 is divisible by 2 but not divisible by 3, so it is not divisible by 6

- 123

We can stop at this point as regardless of whether it is divisible by 3 or not, it will not be divisible by 6. However, for completeness:

1 + 2 + 3 = 6 which is divisible by 3, so it is divisible by 3

â†’ 123 is divisible by 3 but not divisible by 2, so it is not divisible by 6

- 121

We can stop at this point as regardless of whether it is divisible by 3 or not, it will not be divisible by 6. However, for completeness:

1 + 2 + 1 = 4 which is not divisible by 3, so it is not divisible by 3

â†’ 121 is not divisible by either 2 or 3, so it is not divisible by 6

The divisibility rules of 4 and 9 are combined to make the divisibility rule of 36.

Rule: If it is divisible by 2 and by 3Numbers are divisible by 6 if they are divisible by 3 and 2. Therefore, for example, since 18 is divisible by 3 and 2, it is also divisible by 6.The divisibility rule for 6 is, it can go into the number if 2 and 3 can also.

A number has to be even and also divisible by 3.

There is no rule for 7 :P

The divisibility rule for 22 is that the number is divisible by 2 and by 11. Divisibility by 2 requires that the number ends in 0, 2, 4, 6 or 8. Divisibility by 11 requires that the difference between the sum of the the digits in odd positions and the sum of all the digits in even positions is 0 or divisible by 11.

That the last digit is 0. 2 4, 6 or 8.

The divisibility rule for 2 works because the base of our number system, 10, is divisible by 2.

A divisibility rule is a statement of procedures to determine divisibility. For example:"A number is divisible by 2 if it ends with 0, 2, 4, 6 or 8".It does not make any sense to divide such a sentence by 2 or 895 or any other number!
