Herein, is a composite number a even number?
One proof: Because 2 is a divisor of every even number, every even number larger than 2 has at least three distinct positive divisors. So, because all the other even numbers are divisible by themselves, by 1, and by 2, they are all composite (just as all the positive multiples of 3, except 3, itself, are composite).
Is there an even prime number?
Because every even number other than 2 is obviously divisible by 2 and so by definition cannot be prime. The number has only two whole number factors, and itself. There is more than one odd prime number because odd numbers are never divisible by 2.
Is the only even prime number 2?
Two is a prime because it is divisible by only two and one. All the other even numbers are not prime because they are all divisible by two. That leaves only the odd numbers.
