      Common Questions About Prime and Composite Numbers

    Recommended for you

    In simple terms, a prime number is a natural number greater than 1 that has only two distinct positive divisors: 1 and itself. This means that a prime number cannot be divided evenly by any other number except for 1 and itself. On the other hand, a composite number is a natural number greater than 1 that has more than two divisors. In other words, a composite number can be divided evenly by any of its divisors, which can be two or more distinct numbers.

    A prime number can be either odd or even. However, the only even prime number is 2.
