What is the Factorial of 100?

We write the factorial of a number using an exclamation mark (!) after it.

If n is a natural number greater than or equal to 1, then: n! = n × (n - 1) × (n - 2) × (n - 3) × … × 3 × 2 × 1

To find the factorial of 100, we write it as: 100! = 100 × 99 × 98 × … × 3 × 2 × 1

The factorial of 100 is a very large number: 9.33262154439441 × 10^157.

Therefore, the factorial of 100 is approximately 9.33 × 10^157.
