Review: Divisibility into Paperclip Piles
Explanation
The total number of paperclips is divisible by 24 and by
30. To find the smallest such number, we can find the prime factorizations of
24 and 30, by dividing them into factors until we can divide no further. We
have and .
Our total number must therefore have at least three 2's, one 3, and one 5. The
