If you add all the digits up in one number, then divide it by 3 and it comes out even, that number is divisible by 3.
Example: 32,112
3 + 2 + 1 + 1 + 2 = 9
9/3 = 3 So 9 is divisible by 3 and that is how you know if a certain number is divisible by 3.
To list all the numbers divisible by three would be impossible. 3, 6, 9 and just keep adding three until you get to infinity.
