Factorial Me is a skill which calculates and speaks the factorial of a number you provide.

In mathematics, the factorial of a non-negative number n, denoted by n!, is the product of all positive integers less than or equal to n. For example,

5 factorial is 5 x 4 x 3 x 2 x 1 = 120

To get a factorial for a number, say “Alexa, Ask Factorial Me what is the factorial of”, followed by your number.

I can handle large factorials, but struggle when we get over 452 factorial. Believe me, 452 factorial is a very big number!

I use the Conway-Wechsler system to name very large numbers ( http://www.mrob.com/pub/math/largenum.html#conway-wechsler )
