Prime numbers are the smallest set from which all positive integers can be generated by multiplication.

That's about as simple as the definition can be made--and including 1 makes it more complicated, requiring a "and also 1" or something similar.

Before anybody makes this mistake--1 is generated by multiplication. An empty product is by definition, 1.
