You can put this solution on YOUR website! That would be 100 factorial, 100! where n! = n*(n-1)*(n-2)…*(2)*(1) (and n!=1 if n=0).
The first few factorial values:
0! = 1 (by definition)
1! = 1
2! = 2*1 = 2
3! = 3*2*1 = 6
4! = 24
5! = 120
6! = 720
7! = 5040
8! = 40320
9! = 362880
10! = 3628800
From here on, as we increase n, we add at least one more digit, and often 2 more digits, to the factorial calculation n!, so you can see the number will be enormous by the time we get all the way to 100 because we still have 90 more numbers to multiply.

I found a website that has a factorial calculator and they show the answer to be (approximately) .
