Every one of them has an even number of factors.

The factors of all numbers can be written in pairs. With square numbers, one of those pairs is the same number twice. When listed singly, square numbers have an odd number of factors. All others are even.

In mathematics, all nonzero numbers have factors. Some factors are even numbers, some are odd. An even factor is a factor that is an even number.

1 and 2 are factors of all even numbers.

All even numbers greater than 2 are composite because they are divisible by 2 and thus have at least three factors. The number 2, itself, is a prime number because it has only two factors: 1 and itself.

Square numbers have an odd number of factors, all others have an even number. In this context, primes can either be considered as having 0 factors (an even number) or 2 factors - 1 and itself, again, an even number.

Every number except the number 1 has at least two factors, 1 and the number itself. Prime numbers have exactly two factors and composite numbers have more than two factors. All even numbers except the number 2 are composite numbers and have more than two factors. The number 2 is prime and its only factors are 1 and 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.

In mathematics, all nonzero numbers have factors. Some factors are even numbers, some are odd. An even factor is a factor that is an even number.

1 and 2

Not all prime numbers are odd. There is one prime number that is even: 2. A prime number is a number with two and only two factors: 1 (also known as unity) and itself. A composite number is a number with more than two factors. All even numbers are divisible by 2. Thus, all even numbers have 2 as a factor, which means that all even numbers greater than 2 have more than two factors, so they cannot be prime numbers.
