# What is 76 factorial ?

Steps to calculate factorial of 76

## How to calculate the factorial of 76

To find 76 factorial, or 76!, simply use the formula that multiplies the number 76 by all positive whole numbers less than it.

Let's look at how to calculate the Factorial of Seventy-six :

76! is exactly : 1885494701666050254987932260861146558230394535379329335672487982961844043495537923117729972224000000000000000000

Factorial of 76 can be calculated as:
76! = 76 x 75 x 74 x 73 x ... x 3 x 2 x 1

The number of trailing zeros in 76! is 18

The number of digits in 76 factorial is 112.

## What Is Factorial?

A factorial is showed by an integer and an exclamation symbol. In math concepts, factorial is a multiplication function of natural numbers .

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

Symbolically, it is showed as "!".

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

## Factorial Formula

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

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

The expansion of the formula provides the numbers to be multiplied at the same time to find the factorial of the number.

We can also calculate 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 :
76! Factorial = 76 x 75 x 74 x 73 x ... x 3 x 2 x 1 = 76 × 75! = 1885494701666050254987932260861146558230394535379329335672487982961844043495537923117729972224000000000000000000

## 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"
