Let us find the factorial of a smaller number. Say, n = 4. Then 4! = 4 × 3 × 2 × 1 = 24.

Step-by-step explanation
We know that if n is a number, then its factorial is given by

n! = n × (n - 1) × (n - 2) × (n - 3) × ... ... × 1

Here are given number is 100. Thus taking n = 100, we get

100! = 100 × (100 - 1) × (100 - 2) × (100 - 3) × ... ... × 1

= 100 × 99 × 98 × 97 × ... ... × 1

= 93326215443944152681699238856266700490715968264381621468592963895217599993229915608941463976156518286253697920827223758251185210916864000000000000000000000000


What is factorial ?
The factorial is the product of all integers less than or equal to n but greater than or equal to 1. The factorial value of 0 is by definition equal to 1. For negative integers, factorials are not defined. The factorial can be seen as the result of multiplying a sequence of descending natural numbers (such as 3 × 2 × 1).
