What Is Factorial?
A factorial is represented by an integer and an exclamation mark. In Mathematics, factorial is a multiplication operation of natural numbers .
It multiplies the number by every basic number that is less than it .
Symbolically, it is represented as "!".
The function is used, among other things, to find the "n" way things can be arranged .
To find the factorial of any given number, exchange the value for n in the given formula :
n! = n × (n-1) × (n-2) × (n-3) × ….× 3 × 2 × 1
The expansion of the formula provides the numbers to be multiplied together to have the factorial of the number.
We can also measure 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)!
67! Factorial = 67 x 66 x 65 x 64 x ... x 3 x 2 x 1 = 67 × 66! = 36471110918188685288249859096605464427167635314049524593701628500267962436943872000000000000000
What are Factorials Used For?
