Which term refers to numbers that can be divided evenly by numbers other than one and themselves?

The term that refers to numbers that can be divided evenly by numbers other than one and themselves is composite numbers. Composite numbers have at least one additional divisor apart from one and the number itself, meaning they can be factored into smaller integers. For instance, the number 6 can be divided by 1, 2, 3, and 6, making it a composite number because it has divisors other than just 1 and itself.

In contrast, prime numbers are defined as numbers that have exactly two distinct positive divisors: one and the number itself. This means that prime numbers cannot be factored into smaller integers besides 1 and themselves. Rational numbers encompass all numbers that can be expressed as a fraction, including those that are both prime and composite, while irrational numbers are those that cannot be expressed as a simple fraction, such as the square root of 2 or pi. Understanding these definitions helps clarify why composite numbers are specifically those that can be divided evenly by other numbers beyond just one and themselves.
