What are Composite Numbers?

In Mathematics, composite numbers are numbers that have more than two factors.

Note that: Zero (0) is considered as neither prime nor a composite number because it does not have any factors.The smallest composite number is 4.

How to Find the Composite Number?

In order to find a composite number, we find the factors of the given number. If the number has more than two factors, then it is composite.

The procedures to find whether a given number is prime or composite:

Find all the factors of the positive integer

A number is said to be prime if it has only two factors, 1 and itself

If the number has more than two factors, then it is a composite

The best way to figure out a composite number is to perform the divisibility test.

The divisibility test helps us to determine whether a number is a prime or a composite number.

Divisibility means that a number is divided completely (with no remainder) by another number, other than 1 and itself.

To do this, we need to check to see if the number can be divided by these common factors: 2, 3, 5, 7, 11, and 13.

If the given number is even, then start checking with the number 2.

If the number ends with a 0 or 5, then check it by 5.

If the number cannot be divided by any of these given numbers, then the number is a prime number.

What is the properties of Composite Numbers?

1.Composite numbers have more than two factors

2.Composite numbers are evenly divisible by their factors

3.Each composite number is a factor of itself

4.The smallest composite number is 4

5.Each composite number will include at least two prime numbers as its factors (Eg. 10 = 2 x 5, where 2 and 5 are prime numbers)

6.Composite numbers are divisible by other composite numbers also

What are composite numbers between 1 and 100?

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, 42, 44, 45, 46, 48, 49, 50, 51, 52, 54, 55, 56, 57, 58, 60, 62, 63, 64, 65, 66, 68, 69, 70, 72, 74, 75, 76, 77, 78, 80, 81, 82, 84, 85, 86, 87, 88, 90, 91, 92, 93, 94, 95, 96, 98, 99, 100

What are the types of Composite Numbers?

There are two main types of composite numbers in math which are odd composite numbers and even composite numbers.

Odd Composite Numbers

All the odd numbers which are not prime are odd composite numbers. For example, 9, 15, 21, 25, 27 are odd composite numbers.

Even Composite Numbers

All the even numbers which are not prime are even composite numbers. For example, 4, 6, 8, 10, 12, 14, 16, are even composite numbers.
