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.

What does composite means in math?
A composite number is a number that has more than 2 whole number "factors".Factors are numbers that multiply other numbers to get another number.Example:2 * 5 = 101 * 10 = 101, 2, 5, 10 are all factors of 10. Since 10 has four factors, which is greater than 2, it is a composite number!Prime numbers have exactly 2 factors.You can only multiply 1 and 7 to get 7. 7 is prime.1 is neither prime nor composite.
What are math factors?
Math Factors are numbers that divide evenly into another number. For instance 10-the factors would be 1,2,5 and 10 . All numbers divide evenly into 10.
What numbers only have 4 factors?
Numbers that have exactly 4 factors are known as semiprime numbers. Semiprime numbers are the product of two prime numbers, and since prime numbers only have two factors (1 and the number itself), the product of two prime numbers will have a total of 4 factors. Examples of semiprime numbers include 6 (2 x 3) and 15 (3 x 5).
