A Prime number is any number that only has one and itself as factors. Therefore, any number that has more than two factors is not prime. Check the the factors of a number to tell if it is prime or not.
All prime numbers are odd with the only exception of the prime number 2. However, not all odd numbers are prime.
This is because they are only two factors in that number. It may seem to you that all prime numbers odd, but it is not true. Most of them however, are prime numbers. This is why most of the odd numbers are prime numbers.
All prime numbers - except 2 - are odd.
All of the prime numbers are odd except for two.
Except for 2 all other prime numbers are odd. Otherwise, they would be divisible by 2 (and thus not a prime number). This does NOT mean that all odd numbers are prime, but that all prime numbers (aside from 2) are odd.
With exception of the number 2, all prime numbers are odd. However, not all odd numbers are prime.
All prime numbers are odd with the only exception of the prime number 2. However, not all odd numbers are prime.

There are more odd numbers than prime numbers.
All prime numbers are odd, exept of the first prime number 2.
They are odd numbers that do not include prime numbers.

Odd. The only prime number that is even is two. Since there are many prime numbers that are odd (such as 3, 5, etc.), there are more odd prime numbers than even.
All prime numbers are odd except for the number 2.
No, odd numbers such as 9, 15, 21, and 27 are not prime.
Yes. Apart from 2, all prime numbers are odd.
