Question

what is the factorial of 100​

Answer 1

To find:

The factorial of 100

Step-by-step explanation

We know that if n be a number, then its factorial is given by

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

Here our 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

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

Answer:

100! = 93326215443944152681699238856266700490715968264381621468592963895217599993229915608941463976156518286253697920827223758251185210916864000000000000000000000000
