you guys must have no brains in there. it's easy. 0! the only even number that does not get you two.

No, because all even numbers are divisible by two.

Duh, the definition of a prime number is the exact opposite of the definition of an even number.

A number  k (not = 1)  is prime if if it has exactly two divisors, itself and  1 .

An even number  k > 2  is divisible by  1 , 2 , and itself.  So no.

Another rule for Primes is that they cannot be divisible by other Primes.

Even numbers are divisible by 2, so they are not prime.

So no. The only even prime is 2.

NO!!!

Because all other even numbers can be divided by '2' ; they have '2' as a factor.

2 is the only even prime number.

2 is the only known even prime number because like all other prime numbers it has only two factors which are itself and one.

• 3 weeks ago

No, because the number 2 divides evenly into every other even number.

No. Two is the only even prime number. All other even numbers would be divisible by 2 so it can’t be a prime number.
