composite number

A composite number is a positive integer greater than one that has at least one positive divisor other than one and itself. In other words, it can be formed by multiplying two smaller natural numbers. Composite numbers contrast with prime numbers, which have no divisors other than one and themselves. Examples of composite numbers include 4, 6, 8, 9, and 12. Understanding composite numbers is fundamental in number theory and plays a crucial role in various mathematical concepts and applications.
