What Is Factorial?
A factorial is represented by an integer and an exclamation mark. In arithmetic, 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 objects can be arranged .
To find the factorial of any given number, alternate the exact value for n in the given rule :
n! = n × (n-1) × (n-2) × (n-3) × ….× 3 × 2 × 1
The expansion of the formula shows the numbers to be replicated together to find the factorial of the number.
We can also calculate a factorial from the prior one. The factorial of any number is that number multiplied the factorial of (that number minus 1).
So the rule is : n! = n × (n−1)!
6! Factorial = 6 x 5 x 4 x 3 x 2 x 1 = 6 × 5! = 720
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"
