What is the Factorial of 18?
In this article we'll show you how to calculate the factorial of 18 with a really quick, step-by-step explanation of how it's calculated.
First off, what exactly is a factorial? The factorial is the result of multiplying all whole numbers in a chosen number (in this case 18) all the way down to 1.
You will generally see factorials expressed with an exclamation mark after the number, like so:
So let's take 18 and calculate the factorial by multiplying each whole number:
18 x 17 x 16 x 15 x 14 x ... = 6402373705728000
In this case, the number of whole numbers in 18 is more than five. You can see how this can quickly get out of hand with larger numbers.
Factorials are used in math quite a lot when calculating the number of possible combinations or permeatations of something. If you think about shuffling a deck of 52 cards, you can use factorials to calculate how many possible orders there are.
When describing a factorial you would usually say 18! like "18 factorial", "18 shriek", or "18 bang". Personally, I prefer shriek!
Hopefully this article has helped you in your quest to calculate the factorial of 18. Feel free to share with your friends, family, teachers, and anybody who might be interested in factorials of numbers (which is surely everyone!).
