What Is Factorial?
A factorial is represented by an integer and an exclamation mark. In Mathematics, factorial is a multiplication function of natural numbers .
It multiplies the number by every standard number that is less than it .
Symbolically, it is represented as "!".
The function is used, among other things, to find the "n" way pieces can be determined .
To find the factorial of any given number, alternate the value for n in the given method :
n! = n × (n-1) × (n-2) × (n-3) × ….× 3 × 2 × 1
The expansion of the formula provides the numbers to be replicated together with each other to receive the factorial of the number.
We can also work 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)!
83! Factorial = 83 x 82 x 81 x 80 x ... x 3 x 2 x 1 = 83 × 82! = 39455239697206586511897471180120610571436503407643446275224357528369751562996629334879591940103770870906880000000000000000000
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"
