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.

Even numbers are numbers that can be divided by 2 e.g 2,4,6,8,10
All composite numbers are not prime numbers because they have more than two factors
62 and 63 are two examples.
Rectangular numbers are a subset of composite numbers. The squares of prime numbers will be composite but not rectangular.
A composite number is a number which is not prime. All numbers are divided into the categories of either prime or composite (except for the number 1, which is neither). Examples of composite numbers are: 4,6,8,10 etc. All even numbers and square numbers are composite. There are, however, odd and non-square numbers that are composite as well, such as 15,21,27 and 55.

Even numbers are numbers that can be divided by 2 e.g 2,4,6,8,10
Every even number except 2.
30 50 70 because they both end in 0 and 10 is a composite number
All composite numbers are not prime numbers because they have more than two factors
Composite numbers are the non prime numbers and have more than 2 factors. Some examples of composite numbers are 6, 8, 55 etc.
62 and 63 are two examples.
Composite numbers have factors other than 1 and itself. So, two good examples are: 62 and 84
A prime number has only 2 factors which are 1 and itself. Some examples are 3, 5, 7, 11, and 13. Composite numbers are everything else except 1, 2, and 0. Some examples are 4, 6, 8, 10, and 12.
== == 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. == ==
Not all composite numbers are even, but all even numbers except 2 are composite.
