How about 81 or any number that is not a prime number.

Answer:80 is not a prime number. It is a composite number.Definition:A prime number has exactly two factors: 1 (also known as unity) and itself. A composite number has more than two factors; in other words, it has at least one factor besides 1 and itself.Explanation:Any number ending in 0, 2, 4, 6, or 8 is evenly divisible by 2, so it has 2 as a factor. 80 is also divisible by 2, so it is a composite number.
