What Is Factorial?
A factorial is represented by an integer and an exclamation tag. In Mathematics, factorial is a multiplication treatment of natural numbers .
It multiplies the number by every noreal number that is less than it .
Symbolically, it is displayed as "!".
The function is used, among other things, to get the "n" way things can be positioned .
To find the factorial of any given number, change the exact value for n in the given way :
n! = n × (n-1) × (n-2) × (n-3) × ….× 3 × 2 × 1
The expansion of the formula shows the numbers to be replicated together to get 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)!
16! Factorial = 16 x 15 x 14 x 13 x ... x 3 x 2 x 1 = 16 × 15! = 20922789888000
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"
