What are the examples of composite numbers?

Answer 1

Examples of composite numbers include:

-24 because its factors are 1, 2, 3, 4, 6, 8, 12, and 24

-12 because its factors are 1, 2, 3, 4, 6, and 12

-21 because its factors are 1, 3, 7, and 21

-36 because its factors are 1, 2, 3, 4, 6, 9, 12, 18 and 36

-33 because its factors are 1, 3, 11, and 33

-81 because its factors are 1, 9, and 81

-15 because its factors are 1, 3, 5, and 15

Note*: All even numbers except 2 are composite. 2 is an exception because its only factors are 1 and 2.

*Not all odd numbers are prime. Numbers like 21, 15, 33, or 27 are composite.

*1 is not a composite number or a Prime number. For a number to be prime, it should have only two factors: 1 and itself. For a number to be composite, it should have more than two factors. 1 only has one factor.
