Why Is Two The Only Even Prime Number?

First look what a prime number is? A prime number has exactly two distinct natural number divisors: 1 and itself.

An "even number" is an integer which is divisible by 2 with no remainder. The number "two" is divisible only by 2 and 1, and is therefore prime. All other even numbers are divisible by 2 but not by 1.

Two is the only even prime number because only two factors can go into two and they are 1, 2  all the other prime numbers are odd.

But number 2 cannot be prime

Because all even numbers are divisible by '2'. And a prime numbers do have '1' and 'itself' as a divisor. So 2 was the only even prime number. It is divisible by 1'' and '2'.

If a number even then, all numbers can be x by 2, BUT 2 can't be x by any other number BUT ITSELF and 1 of course then it is prime and even. DUH!!!!!!
