# What is 32 factorial ?

Steps to calculate factorial of 32

## How to calculate the factorial of 32

To find 32 factorial, or 32!, simply use the formula that multiplies the number 32 by all positive whole numbers less than it.

Let's look at how to calculate the Factorial of Thirty-two :

32! is exactly : 263130836933693530167218012160000000

Factorial of 32 can be calculated as:
32! = 32 x 31 x 30 x 29 x ... x 3 x 2 x 1

The number of trailing zeros in 32! is 7

The number of digits in 32 factorial is 36.

## What Is Factorial?

A factorial is showed by an integer and an exclamation tag. In Mathematics, 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 objects can be established .

## Factorial Formula

To find the factorial of any given number, alternate the value for n in the given method :

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

The expansion of the formula gives the numbers to be replicated at the same time to get the factorial of the number.

We can also work out 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 :
32! Factorial = 32 x 31 x 30 x 29 x ... x 3 x 2 x 1 = 32 × 31! = 263130836933693530167218012160000000

## 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"
