# What is 95 factorial ?

Steps to calculate factorial of 95

## How to calculate the factorial of 95

To find 95 factorial, or 95!, simply use the formula that multiplies the number 95 by all positive whole numbers less than it.

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

95! is exactly : 10329978488239059262599702099394727095397746340117372869212250571234293987594703124871765375385424468563282236864226607350415360000000000000000000000

Factorial of 95 can be calculated as:
95! = 95 x 94 x 93 x 92 x ... x 3 x 2 x 1

The number of trailing zeros in 95! is 22

The number of digits in 95 factorial is 149.

## What Is Factorial?

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

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

Symbolically, it is showed as "!".

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

## Factorial Formula

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

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

So the rule is : n! = n × (n−1)!

Example :
95! Factorial = 95 x 94 x 93 x 92 x ... x 3 x 2 x 1 = 95 × 94! = 10329978488239059262599702099394727095397746340117372869212250571234293987594703124871765375385424468563282236864226607350415360000000000000000000000

## 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"

## Frequently Asked Questions on Factorial
