Answer:

172 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. 172 is also divisible by 2, so it is a composite number.
