Answer:

A composite number is a whole number which can be composed by multiplying two other whole numbers together, neither of which is 1.

For example, 12 is a composite number because it can be written as 3 x 4 (or 2 x 6). 11 is not a composite number. It can be written only as 1 x 11 because it does not have factors other than 1 and 11. Numbers which are not composite are called prime numbers. A list of composite numbers is given below:

4, 6, 8, 9, 10, 12, 14, 15, 16, 18, 20, 21, 22, 24, 25, 26, 27, 28, 30, 32, 33, 34, 35, 36, 38, 39, 40, 42, 44, 45, 46, 48, 49, 50, 51, 52, 54, 55, 56, 57, 58, 60, 62, 63, 64, 65, 66, 68, 69, 70, 72, 74, 75, 76, 77, 78, 80, 81, 82, 84, 85, 86, 87, 88, 90, 91, 92, 93, 94, 95, 96, 98, 99, 100, 102, 104, 105, 106, 108, 110, 111, 112, 114, 115, 116, 117, 118, 119, 120.
