To know if a number is divisible by 6, you have to first check if it is divisible by 3 and by 2. If it is divisible by 2 and by 3, then it is divisible by 6.
For example: Is 138 divisible by 6?
First, we are going to check if it is divisible by 2: 138 ends in 8, which is an even number, therefore 138 is divisible by 2.
Now, we are going to check if it is divisible by 3 by adding all the digits, 1 + 3 + 8 = 12. As 12 is divisible by 3, then 138 is also divisible by 3.
Since 138 is divisible by both 3 and 2, 138 it is also divisible by 6.
