9)
23624 is divisible by 8 because te last 3 digits (624) are divisible y 8
(624/8 =78)
None of the others are divisible by 8

10) A number is divisible by 6 IF IT'S DIVISIBLE BY 2 AND BY 3:
213 NO

468 is divisible by 2 since the last digit is divisible by 2. It's also divisible by
3 since the sum of its digits [18] is divisible by 3, hence 468 is divisible by 6

621 it's divisible by 3 but NOT by 2, then it's not divisible by 6
