What are Prime and Composite Numbers?

Before we begin, let’s quickly review the definitions of prime and composite numbers.

Prime Numbers:

A prime number is a positive integer that is divisible only by itself and 1. In other words, the only factors of a prime number are 1 and the number itself. Examples of prime numbers include 2, 3, 5, and 7.

Composite Numbers:

A composite number, on the other hand, is a positive integer that has more than two factors. In other words, a composite number can be divided evenly by numbers other than 1 and itself. Examples of composite numbers include 4, 6, 8, and 9.
