Is 512 is divisible by 2, 3, 6 ?

Answer 1

Quick divisibility tests:
- number is divisible by 2 if it ends in an even number, so 512 ends in 2
thus 512 is divisible by 2
- number is divisible by 3 if the sum of its digits is divisible by 3
thus 5+1+2 = 8. But 8 is not divisible by 3, so neither is 512
- number is divisible by 6 if it is divisible by both 2 AND 3, so ...... what do you think?
