# What is 35 factorial ?

Steps to calculate factorial of 35

## How to calculate the factorial of 35

To find 35 factorial, or 35!, simply use the formula that multiplies the number 35 by all positive whole numbers less than it.

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

35! is exactly : 10333147966386144929666651337523200000000

Factorial of 35 can be calculated as:
35! = 35 x 34 x 33 x 32 x ... x 3 x 2 x 1

The number of digits in 35 factorial is 41.

## What Is Factorial?

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

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

Symbolically, it is represented as "!".

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

## Factorial Formula

To find the factorial of any given number, substitute 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 gives the numbers to be replicated to each other to find the factorial of the number.

We can also figure out a factorial from the prior one. The factorial of any number is that number times the factorial of (that number minus 1).

So the rule is : n! = n × (n−1)!

Example :
35! Factorial = 35 x 34 x 33 x 32 x ... x 3 x 2 x 1 = 35 × 34! = 10333147966386144929666651337523200000000

## 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"
