Factorials
The factorial of n is the
product of all positive integers less than or equal to n. It is represented as n!.
An example with n = 8 is
shown below. With that in mind, can you find three sets of numbers (a, b,
c) such that a! × b! = c! and a < b < c < 25?
8! = 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1
