## What Is Factorial?

A factorial is showed by an integer and an exclamation tag. In arithmetic, factorial is a multiplication operation of natural numbers .

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

Symbolically, it is listed as "!".

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

## Factorial Formula

To find the factorial of any given number, exchange 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 numbers to be replicated with each other to receive the factorial of the number.

We can also figure out a factorial from the prior 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 :
44! Factorial = 44 x 43 x 42 x 41 x ... x 3 x 2 x 1 = 44 × 43! = 2658271574788448768043625811014615890319638528000000000

## What are Factorials Used For?

The best use of factorial is in Combinations and Permutations.

Example : Determine how to arrange letters without repeating?

There one way for 1 letter "a":
2 ways for two letters "ab": ab, ba.
There are 6 ways for 3 letters "abc": abc acb cab bac bca.
There are 24 ways for 1234 of the letters "abcd"
