What Is Factorial?
A factorial is represented by an integer and an exclamation symbol. In Mathematics, factorial is a multiplication process 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 get the "n" way things can be organized .
To find the factorial of any given number, exchange the value for n in the given formulation :
n! = n × (n-1) × (n-2) × (n-3) × ….× 3 × 2 × 1
The expansion of the formula provides numbers to be replicated together to receive the factorial of the number.
We can also work out a factorial from the previous 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)!
57! Factorial = 57 x 56 x 55 x 54 x ... x 3 x 2 x 1 = 57 × 56! = 40526919504877216755680601905432322134980384796226602145184481280000000000000
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"
