Divisibility Rule of 6: Rule, Examples

Divisibility Rule of 6

A number is divisible by 6 if it follows two rules at the same time:
1. The number is divisible by 2 (it ends in 0, 2, 4, 6, or 8).
2. The number is divisible by 3 (the sum of its digits is a multiple of 3).

If both rules are true, then the number is divisible by 6.

Steps to Check Divisibility by 6

1. Check if the number is even (it should end in 0, 2, 4, 6, or 8).

2. Add up all the digits and see if the sum is a multiple of 3.

3. If both conditions are true, then the number is divisible by 6!

Examples

Example 1: Is 432 divisible by 6?

1. Check if it’s even: 432 ends in 2 (It’s even).

2. Check sum of digits: 4 + 3 + 2 = 9 (9 is a multiple of 3).

432 is divisible by 6.

Example 2: Is 525 divisible by 6?

1. Check if it’s even: 525 ends in 5 (It’s not even).

2. Check sum of digits: 5 + 2 + 5 = 12 (12 is a multiple of 3).

525 is not divisible by 6.
