Every number above 14! will have zero remainder, since 15 is one of its factors. So, ask the same question about 1! + 2! + 3! + ...14!
All terms greater than 5! have both 3 and 5 as factors, so ask the same question about 1! + 2! + 3! + 4!
That sum is 33. Dividing that by 15 gives 3 with a remainder of 3.
The remainer of the full sum up to 50!divided by 15 will also be 3.
