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

All the herbal numbers which are not element numbers space composite numbers as they can be divided by an ext than 2 numbers. For example, 6 is a composite number due to the fact that it is divisible through 1, 2, 3 and also even through 6.

## What space Composite numbers in Maths?

**Definition 1:** In Mathematics, composite numbers room numbers the have an ext than two factors.

**Definition 2:** The number which deserve to be generated by multiplying the 2 smallest optimistic integers and contain at least one divisor other than the number ‘1’ and itself are recognized as composite numbers. These numbers always have more than 2 factors.

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

### Is 0 a Composite Number?

Zero (0) is thought about as no prime no one a composite number because it does no have any factors.

## Composite numbers Examples

The instances of composite numbers are 6, 14, 25, 30, 52, etc, together 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 above examples, we have the right to see the composite number have more than 2 factors. There space a variety of composite number we deserve to list the end of a set of organic numbers native 1 come 1000 or more. Let us see the list of composite numbers in the next section.

## Properties of Composite Numbers

The nature of composite numbers are straightforward to remember.

Composite numbers have more than 2 factorsComposite numbers are 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 determinants (Eg. 10 = 2 x 5, wherein 2 and 5 are prime numbers)Composite numbers are divisible by various other composite number also## List that Composite Numbers

Here is the perform of composite number from 1 to 100 in Maths. Students have the right to keep a note of this and also also shot to write the numbers beyond 100 because that practice, together composites native 1 come 200 or it rotates 500.

## Composite number 1 to 200

The confident integers having more than two determinants are composite numbers. The list of Composite numbers from 1 come 200 are 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 actions to find whether a provided number is element or composite:

Find all the components of the confident integerA number is said to be prime if it has actually only 2 factors, 1 and itselfIf the number has much more than two factors, then it is a compositeExample: uncover if 14 is a composite number. Let us discover the components of 14.14÷1 = 1414÷2 = 714÷7 = 214÷14 = 1 As we can see, the components of 14 are 1,2,7 and also 14, so it is a composite number. |

## Types that Composite Numbers

There space two main types of composite numbers in Maths i beg your pardon are:

Odd Composite number or Composite odd NumbersEven Composite numbers or Composite also Numbers### Odd Composite Numbers

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

### Even Composite Numbers

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

## Smallest Composite Number

4 is the the smallest composite number.

**Why?**

1 is not a composite number since the single divisor of 1 is 1. The hopeful integers 2 and 3 space prime numbers since it can be separated by only two factors, one and itself. For this reason 2 and 3 are not composite.

But in the instance of number 4, us have much more than two factors. The divisors the 4 are 1,2,4. So this number satisfies the condition of a composite number as mentioned above. ~ 4, 6 is the following composite optimistic integer, i m sorry has factors 1, 2, 3 and 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 Composite Numbers

The difference between the prime numbers and the composite numbers in Maths are provided below:

Prime NumbersComposite Numbers

It can only be divided by 1 and itself, thus have actually only two factors. | It has much more than two components (1 and itself). |

It can only be created as a product of 2 numbers | It deserve to be composed as the product of two or much more numbers |

Example: 5 has determinants are 1 and also 5 | Example: 4 has components are 1, 2 and 4 |
