Composite numbers are positive integers that have integer factors other than itself and 1. The number 12, for example, has factors (other than 1 and 12) of 2, 3, 4, and 6 - that is, any of those numbers can be evenly divided into 12 - and therefore 12 is a composite number. The first few composite numbers are 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, and so on.

What does composite factors mean?
All numbers have factors. Some factors are prime numbers, some are composite numbers, one is neither. The factors of 12 are 1, 2, 3, 4, 6, 12 Since 4, 6 and 12 are composite numbers, they are the composite factors of 12.
What are two composite numbers between 60 and 90?
Composite numbers have factors other than 1 and itself. So, two good examples are: 62 and 84
Are composite numbers even numbers?
Not all composite numbers are even, but all even numbers except 2 are composite.
Can composite numbers have prime numbers as factors?
== == Yes. Once we open the field from integers to composite numbers, the gloves come off and lots of things are possible. Example: 1 1/2 = 3 x 1/3. The factor 3 is prime. All composite numbers have prime numbers as factors. Examples: 4 is a composite number of 2 x 2. 38 is a composite number of 2 x 19. 66 is a composite number of 2 x 3 x 11. == ==
How many composite numbers are there?
The number of composite numbers is infinite.
