What Is Factorial?
A factorial is showed by an integer and an exclamation tag. In arithmetic, factorial is a multiplication procedure of natural numbers .
It multiplies the number by every natural number that is less than it .
Symbolically, it is symbolized as "!".
The function is used, among other things, to find the "n" way elements can be organized .
To find the factorial of any given number, exchange the value for n in the given formula :
n! = n × (n-1) × (n-2) × (n-3) × ….× 3 × 2 × 1
The expansion of the formula gives the numbers to be replicated collectively to get the factorial of the number.
We can also figure out 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)!
97! Factorial = 97 x 96 x 95 x 94 x ... x 3 x 2 x 1 = 97 × 96! = 96192759682482119853328425949563698712343813919172976158104477319333745612481875498805879175589072651261284189679678167647067832320000000000000000000000
What are Factorials Used For?

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"
