# What is 93 factorial ?

Steps to calculate factorial of 93

## How to calculate the factorial of 93

To find 93 factorial, or 93!, simply use the formula that multiplies the number 93 by all positive whole numbers less than it.

Let's look at how to calculate the Factorial of Ninety-three :

93! is exactly : 1156772507081641574759205162306240436214753229576413535186142281213246807121467315215203289516844845303838996289387078090752000000000000000000000

Factorial of 93 can be calculated as:
93! = 93 x 92 x 91 x 90 x ... x 3 x 2 x 1

The number of trailing zeros in 93! is 22

The number of digits in 93 factorial is 145.

## What Is Factorial?

A factorial is represented by an integer and an exclamation tag. 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 displayed as "!".

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

## Factorial Formula

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

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

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

We can also measure 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 :
93! Factorial = 93 x 92 x 91 x 90 x ... x 3 x 2 x 1 = 93 × 92! = 1156772507081641574759205162306240436214753229576413535186142281213246807121467315215203289516844845303838996289387078090752000000000000000000000

## 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"
