What Is Factorial?
A factorial is symbolized by an integer and an exclamation mark. In Mathematics, factorial is a multiplication treatment of natural numbers .
It multiplies the number by every organic number that is less than it .
Symbolically, it is represented as "!".
The function is used, among other things, to get the "n" way items can be structured .
To find the factorial of any given number, replace the exact 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 multiplied with each other to find the factorial of the number.
We can also work 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)!
75! Factorial = 75 x 74 x 73 x 72 x ... x 3 x 2 x 1 = 75 × 74! = 24809140811395398091946477116594033660926243886570122837795894512655842677572867409443815424000000000000000000
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"
