Factorial of 100 or any whole number “n” is defined as the product of all the numbers less than or equal to “n” up to 1.

For instance, the factorial of 4 is 24 because 4 factorial = 4 x 3 x 2 x 1. The character “!” is used to symbolize the factorial of a number. Therefore, the value of 4! is 24.

Factorials have been seen in multiple historical works from Indian, middle eastern and European regions. But the symbol n! was introduced by a French mathematician named **Christian Kramp** in 1808.

Numerous topics in mathematics, including number theory, algebra, geometry, probability, statistics, graph theory, and discrete mathematics, are rooted in the study of factorials.

**Formula of Factorial**

The factorial is simple to calculate. You should be familiar with its formula for this. The factorial-n formula has been provided below for your study

n**!= n x (n-1) x (n-2) x (n-3)… 3 x 2 x 1.**

**Applications of Factorial**

Factorials are widely used in permutations and combinations for example the n choose k formula. Factorials are also used in the binomial theorem. They appear in multiple power series expansions

**Problems**

**1)** Prove that 0! is 1.

**Solution:** Formul to find factorial of n is n!= n x (n-1) … x 1

=> n! = n x (n-1)!

So, if we take 1! it is = 1! x (1-1)!

=> 1= 1.(0!)

=> 1 = 0!

Or which gives 0!= 1.

**What is the formula of factorial?**n! = n × (n – 1) × (n – 2) × … × 1 = n × (n – 1)!
