# What is 41 factorial ?

Steps to calculate factorial of 41

## How to calculate the factorial of 41

To find 41 factorial, or 41!, simply use the formula that multiplies the number 41 by all positive whole numbers less than it.

Let's look at how to calculate the Factorial of Forty-one :

41! is exactly : 33452526613163807108170062053440751665152000000000

Factorial of 41 can be calculated as:
41! = 41 x 40 x 39 x 38 x ... x 3 x 2 x 1

The number of trailing zeros in 41! is 9

The number of digits in 41 factorial is 50.

## What Is Factorial?

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

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

Symbolically, it is symbolized as "!".

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

## Factorial Formula

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

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

The expansion of the formula provides numbers to be replicated with each other 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 replicated the factorial of (that number minus 1).

So the rule is : n! = n × (n−1)!

Example :
41! Factorial = 41 x 40 x 39 x 38 x ... x 3 x 2 x 1 = 41 × 40! = 33452526613163807108170062053440751665152000000000

## 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"
