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.

What are composite numbers give examples?
Composite numbers have more than two factors as for example 9 and 48
Examples of composite and even numbers?
Even numbers are numbers that can be divided by 2 e.g 2,4,6,8,10
What are non-examples of prime numbers?
All composite numbers are not prime numbers because they have more than two factors
What are 2 composite numbers between 60-90?
62 and 63 are two examples.
What is the relationship between composite numbers and rectangular numbers?
Rectangular numbers are a subset of composite numbers. The squares of prime numbers will be composite but not rectangular.
Examples of a composite number?
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.
What are composite numbers give examples?

Even numbers are numbers that can be divided by 2 e.g 2,4,6,8,10
Examples of composite numbers?
Every even number except 2.
What are three examples of composite numbers and tell why they are composite?
30 50 70 because they both end in 0 and 10 is a composite number
What are non-examples of prime numbers?
All composite numbers are not prime numbers because they have more than two factors
What are the numbers belong to composite numbers?
Composite numbers are the non prime numbers and have more than 2 factors. Some examples of composite numbers are 6, 8, 55 etc.
What are 2 composite numbers between 60-90?
62 and 63 are two examples.
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
What is a example of prime and composite numbers?
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.
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. == ==
