Factorial

If you are trying to evaluate the factorial of a whole number ‘n’, then you will have to find the product of that number along with every other whole number below the number ‘n’ till 1. Let’s say, you want to find the factorial of 5. Then you will find the product of numbers 5×4×3×2×1 which is 120. You can use ‘!’ as the symbol for a factorial.

Factorial was seen as an interesting comparison with the change ringing by Fabian Stedman, who was a British author. Change ringing was a part of a musical performance that involved musicians ringing many tuned bells.

Christian Kramp was a French mathematician who suggested the symbol for factorial to be ‘!’.

How Does One Find Factorial Of A Number?

Finding factorial of a number can be written as follows:

n! = n × (n-1) × (n-2) × (n-3) × … × 1

What Is The Factorial Of 100?

If we follow the above formula for finding factorial of 100, then:

100! = 100 × (100-1) × (100-2) × (100-3) × … × 1

= 100 × 99 × 98 × 97 × 96 × … × 1

The result will be =
