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).
