# What is 53 factorial ?

Steps to calculate factorial of 53

## How to calculate the factorial of 53

To find 53 factorial, or 53!, simply use the formula that multiplies the number 53 by all positive whole numbers less than it.

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

53! is exactly : 4274883284060025564298013753389399649690343788366813724672000000000000

Factorial of 53 can be calculated as:
53! = 53 x 52 x 51 x 50 x ... x 3 x 2 x 1

The number of trailing zeros in 53! is 12

The number of digits in 53 factorial is 70.

## What Is Factorial?

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

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

Symbolically, it is showed as "!".

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

## Factorial Formula

To find the factorial of any given number, exchange the exact 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 receive the factorial of the number.

We can also figure out 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 :
53! Factorial = 53 x 52 x 51 x 50 x ... x 3 x 2 x 1 = 53 × 52! = 4274883284060025564298013753389399649690343788366813724672000000000000

## 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

### Can we have factorials for negative numbers ?

Negative number factorials are undefined

### What Is 0!

Zero factorial or Factorial of 0 is simple, and its own value is corresponding to 1. So, 0! = 1.
