no even number greater than 2 is prime so it is composite
40 is a composite number. This is because composite numbers are any number that has more than two factors(one and itself). Therefore, since 2 and 4 to name a few are factors of 40 that makes it a composite 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. 40 has factors other than 1 and itself, so it is not a prime number. For example, it is divisible by 2 because it is an even number. Therefore, 40 is a composite number.
