What Is Factorial?
A factorial is represented by an integer and an exclamation symbol. In arithmetic, factorial is a multiplication treatment of natural numbers .
It multiplies the number by every noreal number that is less than it .
Symbolically, it is listed as "!".
The function is used, among other things, to get the "n" way pieces can be organized .
To find the factorial of any given number, alternate the value for n in the given way :
n! = n × (n-1) × (n-2) × (n-3) × ….× 3 × 2 × 1
The expansion of the formula gives the numbers to be multiplied together with each other to obtain the factorial of the number.
We can also calculate a factorial from the previous 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)!
51! Factorial = 51 x 50 x 49 x 48 x ... x 3 x 2 x 1 = 51 × 50! = 1551118753287382280224243016469303211063259720016986112000000000000
