Q:
# Is 2 a Prime Number?

**Yes, 2 is a prime number.** In fact, 2 is the only even number that is prime. A prime number is a number that has only two factors, the number 1 and itself.

If a number has more than two factors, it is called a composite number. All even numbers have 2 as a factor because they are divisible by 2. Thus, even numbers other than 2 cannot be prime.

All other even numbers are classified as composite numbers. A composite number is a positive number that has at least one positive factor other than itself and 1. Four is the smallest composite number.

The number 1 is called a special number, as it has only one factor. It is neither prime nor composite. Prime numbers are odd numbers, but not all odd numbers are prime. For instance, 3 is both a prime number and an odd number. However, 33 is an odd number but not a prime number.
