The reason why 1 is said not to be a prime number is merely convenience.

Ah... OK, sure, analogous to defining 0! = 1.


For example, if 1 was prime then the prime factorization of 6 would not be
unique since 2 times 3 = 1 times 2 times 3. A number that can be written as
a product of prime numbers is composite. Thus there are three types of
natural numbers: primes, composites, and 1.

Makes perfect sense :-) -ml-
