All prime numbers except for 2 are odd?
All of the prime numbers are odd except for two.
Is a prime number odd?
All prime numbers are odd except one prime number and that is 2.
Is a prime number always an odd number?
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.
What group of numbers even or odd contain more prime numbers?
All even numbers except 2 are divisible and thus not prime. There is no such number for odd numbers, and there is in fact just one even prime and infinitely many odd primes.
Is 570 a prime number?
No, all prime numbers except the number 2 are odd numbers. 570 is an even number so it can't be a prime.
