let s be the set of all positive integers n such that n squared is a multiple of both 24 and 108. which of the following integers are divisors of every integer n in s. indicate all such integers

[a] 12

[b] 24

[c] 36

[d] 72

Here, Greg told that the answer will be 12 and 36. However, I think 72 should also be a result. Please clarify me.
