## What Is Factorial?

A factorial is displayed by an integer and an exclamation tag. In math concepts, factorial is a multiplication treatment of natural numbers .

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

Symbolically, it is listed as "!".

The function is used, among other things, to get the "n" way pieces can be positioned .

## Factorial Formula

To find the factorial of any given number, substitute the value for n in the given way :

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

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

We can also work out a factorial from the prior one. The factorial of any number is that number times the factorial of (that number minus 1).

So the rule is : n! = n × (n−1)!

Example :
94! Factorial = 94 x 93 x 92 x 91 x ... x 3 x 2 x 1 = 94 × 93! = 108736615665674308027365285256786601004186803580182872307497374434045199869417927630229109214583415458560865651202385340530688000000000000000000000

## What are Factorials Used For?
