Why can a prime number not have 0 in it?

Lots of prime numbers have zeros in them. 101, 103, 107 and 109 are all prime numbers. Prime numbers can't end in zero. Numbers that end in zero are multiples of ten and have too many factors to be prime numbers.


If 0 and 1 are not composite or prime numbers then what are they?

First, zero is not applied to the terms prime and composite because the definitions only apply to natural numbers (positive whole numbers, which does not include zero). One is not prime or composite because one is the unit that is used within the definition of prime of composite numbers, and many definitions of prime and composite even exclude one from the definition. If you want to categorize one within a discussion of prime and composite, it is common to simply call one the unit.
