Composite Numbers

Numbers can be classified on the basis of the number of factors they have. If a number has just two factors - 1 and the number itself, then it is a prime number. However, most numbers have more than two factors, and they are called composite numbers. On this page, we will learn the difference between prime and composite numbers, the smallest composite number, and odd composite numbers. The last one is interesting because there are several odd composite numbers, unlike 2, which is the only even prime number.

What are Composite Numbers?

Composite numbers can be defined as natural numbers that have more than two factors. In other words, a number which is divisible by a number other than 1 and the number itself, is called a composite number. Let’s learn more about composite numbers with examples.

Examples of Composite Numbers

4, 6, 8, 9, and 10 are the first few composite numbers. Let's take 4 and 6. In the above example, 4 and 6 are called composite numbers because they are made by combining other numbers. This idea is important and we used it in a theorem called the Fundamental Theorem of Arithmetic. Let's proceed to understand the important features of composite numbers.

Properties of Composite Numbers

A composite number is a positive integer that can be formed by multiplying two smaller positive integers. Note the properties of a composite number listed below:

All composite numbers are evenly divisible by smaller numbers that can be prime or composite.

Every composite number is made up of two or more prime numbers.

Let us have a look at the properties of the composite number 72 in order to understand the concept in a better way.
