What Is Factorial?
A factorial is displayed by an integer and an exclamation symbol. In arithmetic, factorial is a multiplication process 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 find the "n" way objects can be organized .
To find the factorial of any given number, alternate 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 provides the numbers to be multiplied collectively to obtain the factorial of the number.
We can also figure 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)!
27! Factorial = 27 x 26 x 25 x 24 x ... x 3 x 2 x 1 = 27 × 26! = 10888869450418352160768000000
