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
