The only number that is both prime and odd is the number 2. This is because a Prime number is defined as a number greater than 1 that has no positive divisors other than 1 and itself. Since 2 is the only even prime number, all other prime numbers are odd.

Which is the smallest odd prime number?
3 is the smallest odd prime number.
What is a prime number times a prime number?
A prime number times a prime number is a composite number. Since prime numbers, except for 2, are odd numbers, a prime number times a prime number is usually an odd number. It will only be an even number if one of the prime numbers is 2. A prime number times a prime number will be a number with four factors unless both prime numbers are the same, in which case it will be a square number with only three factors.
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.
