👉 The term "noncomposite" refers to a number that is not a product of two or more other natural numbers. In other words, it is a number that cannot be expressed as a product of two or more smaller numbers. For example, 7 is not a composite number because it can be divided by 1 and itself (7 = 7). Noncomposite numbers are used in many areas of mathematics, including algebra, geometry, and number theory.
