In Mathematics, composite numbers room numbers the have an ext than two factors. This numbers are also called composites. Composite number are just the the opposite of prime numbers which have actually only 2 factors, i.e. 1 and also the number itself.

All the herbal numbers which space not element numbers room composite numbers together they can be separated by much more than 2 numbers. Because that example, 6 is a composite number due to the fact that it is divisible through 1, 2, 3 and also even through 6.

In this article, us will learn the list of composite numbers, smallest composite number, strange composite numbers along examples.

## What room Composite numbers in Maths?

Definition 1: In Mathematics, composite numbers space numbers the have more than two factors.

Definition 2: The numbers which have the right to be generated by multiply the 2 smallest confident integers and also contain at the very least one divisor various other than the number ‘1’ and itself are known as composite numbers. These numbers always have more than two factors.

Fact: any type of even number i m sorry is greater than 2 is a composite number.

### Is 0 a Composite Number?

Zero (0) is considered as neither prime nor a composite number due to the fact that it does not have any type of factors.

## Composite number Examples

The instances of composite numbers room 6, 14, 25, 30, 52, etc, such that:

 Composite numbers Factors 6 1, 2, 3, 6 14 1, 2, 7, 14 25 1, 5, 25 30 1, 2, 3, 5, 6, 10, 15, 30 52 1, 2, 4, 13, 26, 52

In every the over examples, we can see the composite numbers have an ext than 2 factors. There space a number of composite number we can list out of a collection of natural numbers indigenous 1 come 1000 or more. Let united state see the perform of composite numbers in the next section.

## Properties that Composite Numbers

The properties of composite numbers are easy to remember.

Composite number have much more than two factorsComposite numbers room evenly divisible by their factorsEach composite number is a element of itselfThe the smallest composite number is 4Each composite number will encompass at least two prime numbers together its components (Eg. 10 = 2 x 5, wherein 2 and also 5 are prime numbers)Composite numbers room divisible by other composite number also

## List the Composite Numbers

Here is the perform of composite numbers from 1 come 100 in Maths. Students can keep a note of this and also also shot to compose the numbers past 100 because that practice, such composites indigenous 1 come 200 or it spins 500.

## Composite numbers 1 come 200

The confident integers having an ext than two components are composite numbers. The list of Composite numbers from 1 come 200 space given listed below in the table.

 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, 102, 104, 105, 106, 108, 110, 111, 112, 114, 115, 116, 117, 118, 119, 120, 121, 122, 123, 124, 125, 126, 128, 129, 130, 132, 133, 134, 135, 136, 138, 140, 141, 142, 143, 144, 145, 146, 147, 148, 150, 152, 154, 155, 156, 157, 158, 159, 160, 162, 164, 165, 166, 168, 170, 172, 174, 175, 176, 177, 178, 180, 182, 184, 185, 186, 187, 188, 189, 190, 192, 194, 195, 196, and 198.

## How to find the Composite Number?

The steps to find whether a offered number is element or composite:

Find all the determinants of the confident integerA number is claimed to be prime if it has only 2 factors, 1 and itselfIf the number has much more than 2 factors, climate it is a composite
 Example: find if 14 is a composite number. Let us find the components of 14.14÷1 = 1414÷2 = 714÷7 = 214÷14 = 1As we have the right to see, the components of 14 room 1,2,7 and also 14, so it is a composite number.

## Types the Composite Numbers

There room two main types of composite numbers in Maths which are:

Odd Composite numbers or Composite weird NumbersEven Composite numbers or Composite also Numbers

### Odd Composite Numbers

All the weird integers which room not prime are odd composite numbers. Examples of composite strange numbers space 9, 15, 21, 25, 27, 31, etc.

### Even Composite Numbers

All the also integers which are not element are even composite numbers. Instances of even composite numbers room 4, 6, 8, 10, 12, 14, 16, etc.

## Smallest Composite Number

4 is the smallest composite number.

Why?

1 is no a composite number because the sole divisor of 1 is 1. The confident integers 2 and 3 are prime numbers due to the fact that it have the right to be divided by just two factors, one and also itself. Hence 2 and also 3 room not composite.

But in the case of number 4, us have an ext than 2 factors. The divisors that 4 space 1,2,4. Therefore this number satisfies the problem of a composite number as discussed above. After ~ 4, 6 is the following composite positive integer, i beg your pardon has determinants 1, 2, 3 and also 6.

Hence, 4 is the the smallest composite number (Proved).

 Important note on Composite numbersSmallest Composite Number = 4Smallest prime Number = 2Smallest strange Composite Number = 9Two-digit the smallest Composite Number = 10

## Difference between Prime and also Composite Numbers

The difference between the element numbers and also the composite numbers in Maths are detailed below:

Prime NumbersComposite Numbers
It have the right to only be separated by 1 and itself, thus have actually only 2 factors.It has much more than two components (1 and itself).
It have the right to only be created as a product of two numbersIt have the right to be written as the product of 2 or an ext numbers
Example: 5 has components are 1 and also 5Example: 4 has determinants are 1, 2 and also 4

## Frequently Asked questions on Composite Numbers

### What is a composite number?

A composite number is a natural number or a optimistic integer i beg your pardon has much more than two factors. Because that example, 15 has components 1, 3, 5 and 15, for this reason it is a composite number.

### Is 2 a composite number?
