On this section of Math Worksheets, we discuss a list of Composite numbers. A list of Composite numbers contains numbers with more than two factors, the Composite numbers. The list of Composite numbers show that every composite number can be written as the product of Prime numbers. When studying factors and multiples, you will most likely come across a list of Composite numbers.

In Addition to the list of Composite numbers, explore the following related topics to list of Composite numbers.

From the previous list of composite numbers from 1 to 100 (the list of the first 100 composite numbers), we can count the number of composite numbers as follow. The following list of composite numbers will answer the question of how many composite numbers there are between two numbers.

List of composite numbers from 1 to 10

There are 5 composite numbers from 1 to 10: 4 6 8 9 10

List of composite numbers from 10 to 20

There are 6 composite numbers from 10 to 20: 12 14 15 16 18 20

Prime and composite numbers are often referred to hand in hand. Odd numbers and even numbers can be composite numbers.

What is a composite number?

A composite number is a counting number that is not a prime number. Composite numbers are numbers that have more than two factors. Composite numbers are different from Prime numbers because Prime numbers have two factors, one and itself whereas composite numbers have one, itself and another number. This is the composite number definition.
