A composite number is defined as a natural number greater than 1 that has multiple factors, meaning it can be divided evenly by more numbers than just 1 and itself. For example, the number 6 can be divided evenly by 1, 2, 3, and 6. This characteristic distinguishes composite numbers from prime numbers, which have exactly two distinct positive divisors: 1 and the number itself.

In this context, the other choices do not accurately describe composite numbers. For instance, a number that cannot be divided evenly refers to prime numbers or even the number 1, which is neither prime nor composite. The third option describes a prime number, while the fourth option incorrectly discusses negative numbers, which do not fall under the same classification as composite or prime numbers, as these terms are typically applied to natural numbers. Therefore, the identification of composite numbers as those natural numbers greater than 1 with multiple factors is essential for understanding mathematical classifications.
