Composite A prime number is a number that has only two factors (itself and one) A composite number is a number that has more than two factors.

prime means it has only 2 factors which is itself and 1. composite has in addition to 1 and itself.

A prime number is any number that only has one and itself as factors. Therefore, to tell if a number is prime simply find it's factors. If it has more than two factors than it is not a prime number, it is composite.

Composite. Since it is very easy to decipher if 34 is prime or composite, I assume you are unfamiliar with the definitions of prime and composite. A prime number is a number that has only two factors: 1 and itself. A composite number is a number that has more than 2 factors: 1, itself, and other(s). You can immediately tell that 34 is composite because it is even, and the number two is the only EVEN number that is prime.

The number five is a prime number because its only factors are 1 and itself. To be a composite number, a number has to have more than those two factors.
