No, all odd numbers are not prime numbers. A Prime number is a number such that it can only be evenly divided by 1 and itself. 9, for example, is not prime, because it is divisable by 3. The first few primes are 2,3,5,7,11,13,17,19,23,29,31,37,...
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.
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 one prime number and that is 2.
Not all odd numbers are prime. Prime means you can only divid a number by itself.
2 is the only prime number that is not an odd number.
All prime numbers other than 2 are odd numbers. 2 is the only even prime number.
All prime numbers are not odd. 2 is a prime, 2 is not odd.
Actually 2 is a prime number so not all are odd primes.
All prime numbers are odd except for the number 2.
Yes, every prime number, except for the number 2, is odd.
Find a prime number that is even. 2.
All even numbers are, by definition, multiples of 2 and therefore are not prime. It follows that every prime number (other than 2) is odd as a prime number is defined as one which is not the multiple of any other integers. This is not to say that all odd numbers are prime. Odd and prime: 3, 5, 7, 11, 13, 17, 19 etc...
