What are compsite numbers?

Composite numbers are natural numbers greater than one that have more than two distinct positive divisors, meaning they can be divided evenly by numbers other than one and themselves. For example, 4, 6, and 9 are composite numbers because they can be divided by 1, themselves, and at least one other number (like 2 for 4, or 3 for 9). In contrast, prime numbers, such as 2, 3, and 5, have exactly two distinct positive divisors: 1 and themselves.
