## What Is Factorial?

A factorial is displayed by an integer and an exclamation mark. In Mathematics, factorial is a multiplication function of natural numbers .

It multiplies the number by every natural number that is less than it .

Symbolically, it is symbolized as "!".

The function is used, among other things, to find the "n" way things can be organized .

## Factorial Formula

To find the factorial of any given number, replace the exact value for n in the given equation :

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

The expansion of the formula provides the numbers to be multiplied together with each other to obtain the factorial of the number.

We can also figure out a factorial from the previous one. The factorial of any number is that number multiplied the factorial of (that number minus 1).

So the rule is : n! = n × (n−1)!

Example :
62! Factorial = 62 x 61 x 60 x 59 x ... x 3 x 2 x 1 = 62 × 61! = 31469973260387937525653122354950764088012280797258232192163168247821107200000000000000

## What are Factorials Used For?
