If m is the smallest positive integer such that m! is a multiple of 4125, and n is the smallest positive integer such that n! is a multiple of 281600, then find n-m.
Thanks for helping!
n - m = 5.
looks like that's wrong
The smallest m = 15 and the smallest n = 16
n - m = 16 - 15 = 1
erm... that's incorrect
m = 15 and n = 13
n - m = - 2
@pocketthepenguin has this been verified, or shall I give it a shot?
+85
