What Is Factorial?
A factorial is displayed by an integer and an exclamation symbol. In Mathematics, factorial is a multiplication procedure of natural numbers .
It multiplies the number by every natural number that is less than it .
Symbolically, it is represented as "!".
The function is used, among other things, to find the "n" way items can be structured .
To find the factorial of any given number, change the value for n in the given method :
n! = n × (n-1) × (n-2) × (n-3) × ….× 3 × 2 × 1
The expansion of the formula gives the numbers to be replicated together with each other to have the factorial of the number.
We can also figure out a factorial from the previous 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)!
98! Factorial = 98 x 97 x 96 x 95 x ... x 3 x 2 x 1 = 98 × 97! = 9426890448883247745626185743057242473809693764078951663494238777294707070023223798882976159207729119823605850588608460429412647567360000000000000000000000
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"
