The only Prime number which isn't odd is the number 2. As the only things it is divisible by is 2 and 1. Therefore is prime. All other even numbers can be divided by 2, so are not prime.

No, the product of 2 prime numbers is not always even. If one of the prime numbers is 2, then the product will be even. However, if both prime numbers are odd, then the product will be odd.

That isn't possible. The sum of three odd numbers will always be odd. You can make the sum of 3 prime numbers equal to 32 if one of them is 2 (which is not odd).

No, they do not. If one of the prime numbers is 2, you will have an odd number.

no

You don't always. 2 + 5 = 7, for example. But all prime numbers other than 2 are odd and two odd numbers always equal an even number when added together.

No.

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.

All prime numbers have only 2 factors which are themselves and one. Al prime numbers are odd numbers except for 2 which is the only even prime number.

Prime numbers are whole numbers that are not divisible by anything but one and itself. Examples of prime numbers include 1;2;3;5;7;9... etc. Prime numbers must always be odd (except for 2) but not all odd numbers are prime. For example, 21 is odd, but it is divisible by 3 and 7. Therefore, it is not prime.

Not quite.When two prime numbers of 3 and higher are added together, the result is always even, because all such prime numbers are odd numbers, and when two odd numbers are added together, the result is always an even number.However 2 is a prime number, and 2 is also an even number. Adding 2 (an even number) to a different prime number (an odd number) will always yield an odd number.Only if you don't include "2".

No. The sum of two odd numbers is always even, and no prime is even (apart from 2, but it is the lowest prime, so no primes can be added to form it).

No, they do not. If one of the prime numbers is 2, you will have an odd number.

Because evens can always be divided by 2
