Any multiple of 3 is divisible by 3. 3 x 1 = 3
3 x 2 = 6
3 x 3 = 9
3 x 4 = 12
3 x 5 = 15
3 x 6 = 18
3 x 7 = 21
3 x 8 = 24
3 x 9 = 27
3 x 10 = 30 The digits of a number that is divisible by 3 will add up to a number that is divisible by 3. For example, 1230 has digits that add up to 6, so it is divisible by 3. As another example, 15762 has digits that add up to 21, so it is divisible by 3.
If your initial result is too large for you to know if it is divisible by 3, add up the digits of the new number to see if it is divisible by 3. For example, 155837955 has digits that add up to 48, whose digits add up to 12, so it is divisible by 3.
