Composite numbers have at least 3 factors. There are no composite numbers with only one factor. There are numbers that have the factor multiplied by itself: Some of them are:
4 - 2 x 2
9 - 3 x 3
16 - 4 x 4
25 - 5 x 5
36 - 6 x 6
49 - 7 x 7
64 - 8 x 8
81 - 9 x 9
100 - 10 x 10
etc.

Composite numbers have more than two factors.
The greatest common factor of these numbers is 1. If it were a composite number, we could say that that number, and all the numbers that divide it evenly, divide these numbers evenly. However, these numbers are relatively prime-that is, the only factor they share is 1.
Not all composite numbers are even, but all even numbers except 2 are composite.
The 'opposite' status of a number that is not prime is a composite number.Except for 0 and 1, all numbers that are not prime (i.e. they are multiples of other numbers) are called composite numbers.The opposite of a prime number would be a number that is not prime. Almost all numbers that are not prime are composite numbers. A prime number is a number that has exactly two factors. A composite number has more than two factors. However, composite numbers do not include all numbers that are not prime. The number 1 has only one factor, so it is neither prime nor composite - it is unity.
All even numbers are composite except 2 which is a prime numberAll but 2.
