All of the integers >= 1 that have only 2 divisors...1  and the number itself    1 3 5     19   23       83   etc etc   (there are lots in between my examples)

A prime is a natural number that has no positive divisors other than 1 and itself

 

2 is the only even prime

 

The rest are   3, 5, 7, 11, 13, 17........etc.

 

 

 

cool cool cool

Thanx for the correction Chris.....   '1' by the definition is not considered a prime number.
