Review: A prime number is a whole number greater than zero that has exactly two different factors, one and itself. For example, the number 3 is a prime number because its only factors are 1 and 3. In contrast, a composite number is a whole number greater than zero that has more than two different factors. The number 6 is a composite number because its factors are 1, 6, 2, and 3.
It’s important to note that the number 1 is neither prime nor composite. It is not prime because it does not have exactly two different factors. And it is not composite because it does not have more than two factors. 1 is a special number.
