Numbers that have exactly 2 factors under 10 are prime numbers. Prime numbers are integers greater than 1 that have no positive divisors other than 1 and themselves. Examples of prime numbers under 10 are 2, 3, 5, and 7. These numbers have only two factors, 1 and the number itself.

Well, honey, the numbers under 10 that have exactly 2 factors are called prime numbers. So, we're talking about 2, 3, 5, and 7. They're like the cool kids in math class, strutting around with only themselves and 1 as factors.
