factors branch out from the previous factors until all of the
factors are prime numbers.
A monomial expressed as a product of prime numbers and
variables with no variable having an exponent greater than 1.
The expression of n!, read n factorial, where n is greater than
zero, is the product of all positive integers beginning with n and
counting backward to 1. Example: 5! = 5 × 4 × 3 × 2 × 1 = 120
