To figure out whether 4,320 is divisible by these numbers, we can use their divisibility rules to help us out.

A number is divisible by 3 or 9 if its digits add up to a number divisible by 3 or 9. The digits of 4,320 add to 4 + 3 + 2 + 0 = 9, which is divisible by both 3 and 9, so 4,320 is divisible by 3 and 9.
