While all prime numbers are odd (except 2), not all odd numbers are prime. 9 for example is an odd number, but you can get it by multiplying 3X3, so it is not prime. Odd numbers are numbers that are not divisible by 2. Prime numbers are numbers that cannot be generated by multiplying 2 whole numbers besides 1 and itself.

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.

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.

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 of the prime numbers are odd except for two.

All prime numbers are odd, exept of the first prime number 2.

All prime numbers are not odd numbers. 2 is an even prime number, and it is the only even prime number because all other even numbers have 2 as one of their factors.

no, 25 is odd and is not prime 25 = 5 x 5 There is only one even prime number:2, all other prime numbers are odd, but all odd numbers are not prime number

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.

All prime numbers are not odd. 2 is a prime, 2 is not odd.

No. 9 is not prime.

There is an infinite amount of prime numbers all of which are odd numbers

All prime numbers are odd except for 2 which is the only even prime number

All prime numbers - except 2 - are odd.

2 is the only prime number that is not an odd number.

The question, "the" three odd prime numbers, is wrong. There are much more than three odd prime numbers - in fact, infinitely many. There are infinitely many prime numbers, and all except the number 2 are odd.

Not all odd numbers are prime. Prime means you can only divid a number by itself.

All prime numbers are odd numbers. If one were even, it would be divisible by two and would, therefore, not be prime.

The aren't. Two is even and is a prime number. There are many odd, composite numbers.

Prime numbers are integers that are not divisible by anything except one and themselves. All prime numbers (excepting two) are odd.

'25' is odd, all right, but not prime. (It can be divided by 1, 5, and 25) By the way, prime numbers must be odd numbers. All even numbers can be divided by 2, at least, and are therefore not prime.

All of them. 100%. All prime numbers are odd numbers. (The exception being the number 2)
