A factorial is a math operation. Google explains it well:

```
Factorials are very simple things.
They're just products, indicated by an exclamation mark.
For instance, "four factorial" is written as "4!" and means 1Ã—2Ã—3Ã—4 = 24.
In general, n! ("enn factorial") means the product of all the whole numbers from 1 to n; that is, n! = 1Ã—2Ã—3Ã—...Ã—n.
