Answer 7
5! is divisible by 15
n! will be divisible by 15 if n5
1! 2! 3! 4!
= 1 2 6 24
= 33
33 = 152 3
12.66666667
n
i! = 15a 3 if n5
i=1
5! is divisible by 15 and so are all factorials that come after it.
So we only need to find the remainder for 1! 2! 3! 4!
1! = 1 : remainder is 1
2! = 2 : remainder is 2
3! = 6 : remainder is 6
4! = 24 : remainder is 9
