First of all, remember that a Prime number is a number which is only divisible by either 1 or the number itself. This statements also means that the Prime number has only two factors, which are 1 and the number itself.
This means any number which has more than two factors are not prime. So, first we should look at the number Two (2). 2 has only two factors: 1 and 2 . All even numbers are divisible by 2. Thus, 2 can exactly divide any even number greater than it, and also become a factor of it.
Then, it is clear that Every even number greater than 2 has more than two factors, which implies that every even number greater than 2 is not prime.
