How to Find Factorial?
A factorial of a number is defined as a function which multiplies the number by every natural number below it. Symbolically the factorial can be represented as "!"
So, n factorial is the product of first n natural numbers, represented as n!
Factorial n! = n (n-1) (n-2) …………………….(3)(2)(1) or n! = n (n-1)!
Find the 5!
Factorial n! = n (n-1) (n-2) …………………….(3)(2)(1)
= 5 (5 - 1) (5 - 2) (5 - 3) (5 - 4) (5 - 5)!
= 5 × 4 × 3 × 2 × 1 × 0! [0! = 1]
Similarly, you can try the calculator to find the factorial of any number
