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 natural number that is less than it .

Symbolically, it is showed as "!".

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

Factorial Formula

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

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

The expansion of the formula shows the numbers to be multiplied 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 multiplied the factorial of (that number minus 1).

So the rule is : n! = n × (n−1)!

Example :
37! Factorial = 37 x 36 x 35 x 34 x ... x 3 x 2 x 1 = 37 × 36! = 13763753091226345046315979581580902400000000
