Is 49 a composite number or a prime number?

A Prime number is a number with two and only two factors: 1 (also known as unity) and itself. A composite number is a number with more than two factors; in other Words, it has at least one factor besides 1 and itself. 49 has factors other than 1 and itself, so it is not a prime number. For example, it is divisible by 7. Therefore, 49 is a composite number.
