If a whole number is divisible by 2, 3, 4, and 5, then it
must be divisible by which number?

6 and/or 10

it should be either 6 or 10 because you have to find the leas common multiple that all these numbers share. the largest number here is 5, so i found all the multiples of 5. the first number i found that has factors of all these numbers is 60.

yes? sounds right, but you didn’t ask a question.

a and c are the answeres
