# How do you use the factorial notation n! in Excel?

I need to calculate data in a table and part of the equation has the factorial notation n! (3!=3x2x1). How can I put this into the equation in Excel? I can’t seem to be able to just use the exclamation mark.

• =FACT(num)

For example to get 3! use

=FACT(3)
