What Is Factorial?
A factorial is symbolized by an integer and an exclamation mark. In arithmetic, factorial is a multiplication process of natural numbers .
It multiplies the number by every organic number that is less than it .
Symbolically, it is represented as "!".
The function is used, among other things, to find the "n" way items can be positioned .
To find the factorial of any given number, substitute 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 gives the numbers to be multiplied together to get the factorial of the number.
We can also determine a factorial from the previous one. The factorial of any number is that number times the factorial of (that number minus 1).
So the rule is : n! = n × (n−1)!
29! Factorial = 29 x 28 x 27 x 26 x ... x 3 x 2 x 1 = 29 × 28! = 8841761993739701954543616000000
