If it's even and divisible by 3, it's divisible by 6.
What are the last numbers so that 3 is the divisible?
Divisibility if a number by 3 is not determined by its last digits: instead it is determined by the number's digital root.You get the digital root of a number by adding together all its digits. If the answer is a big number, then find the digital root of the answer. Keep going until you have a number that is smaller than 10. If this number is 3, 6 or 9 (all divisible by 3) then the original number is divisible by 3. And it not, it is not.
