Almost all prime numbers are odd. The number 2 is an exception, it is the only even Prime number. Prime numbers are numbers which are evenly divisible only by themselves, and the number 1. Which is to say, they have no factors. So when factoring a number, the smallest factors are prime numbers. Any numbers that are not prime have factors.

Prime number: A whole number only divisible by itself and 1.

Odd number: A whole number that does not have a factor that is 2.

With exception of the number 2, all prime numbers are odd. However, not all odd numbers are prime.

No because 2 is the only even prime number but in general odd prime numbers have only two factors which are themselves and one
