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

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

In this article, us will discover the perform of composite numbers, the smallest composite number, odd composite numbers follow me examples.

What room Composite numbers in Maths?

Definition 1: In Mathematics, composite numbers are numbers the have an ext than 2 factors.

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

Fact: any even number i m sorry is better than 2 is a composite number.

Is 0 a Composite Number?

Zero (0) is considered as neither prime no one a composite number since it does no have any type of factors.

Composite numbers Examples

The examples of composite numbers are 6, 14, 25, 30, 52, etc, together that:


Composite numbersFactors
6 1, 2, 3, 6
141, 2, 7, 14
251, 5, 25
301, 2, 3, 5, 6, 10, 15, 30
521, 2, 4, 13, 26, 52

In every the over examples, we deserve to see the composite numbers have much more than 2 factors. There are a number of composite number we can list the end of a set of herbal numbers from 1 come 1000 or more. Let united state see the perform of composite numbers in the following section.

Properties the Composite Numbers

The nature of composite number are simple to remember.

Composite numbers have much more than two factorsComposite numbers are evenly divisible by your factorsEach composite number is a element of itselfThe smallest composite number is 4Each composite number will include at the very least two element numbers as its determinants (Eg. 10 = 2 x 5, where 2 and also 5 room prime numbers)Composite numbers space divisible by other composite number also

List that Composite Numbers

Here is the list of composite numbers from 1 come 100 in Maths. Students can keep a keep in mind of this and also also try to write the numbers beyond 100 for practice, together composites indigenous 1 to 200 or it spins 500.

Composite number 1 to 200

The hopeful integers having more than two factors are composite numbers. The list of Composite number from 1 to 200 room given 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 procedures to discover whether a offered number is element or composite:

Find every the determinants of the confident integerA number is said to be prime if it has actually only two factors, 1 and also itselfIf the number has more than 2 factors, climate it is a composite
Example: uncover if 14 is a composite number. Let us find the factors of 14.14÷1 = 1414÷2 = 714÷7 = 214÷14 = 1

As we deserve to see, the determinants of 14 are 1,2,7 and 14, so that is a composite number.


Types of Composite Numbers

There are two main species of composite numbers in Maths i m sorry are:

Odd Composite numbers or Composite strange NumbersEven Composite number or Composite even Numbers

Odd Composite Numbers

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

Even Composite Numbers

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

Smallest Composite Number

4 is the smallest composite number.

Why?

1 is no a composite number since the single divisor the 1 is 1. The optimistic integers 2 and 3 space prime numbers since it can be divided by just two factors, one and also itself. Thus 2 and 3 space not composite.

But in the situation of number 4, us have more than two factors. The divisors of 4 space 1,2,4. For this reason this number satisfies the condition of a composite number as mentioned above. After ~ 4, 6 is the following composite hopeful integer, i beg your pardon has determinants 1, 2, 3 and 6.

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


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

Difference in between Prime and Composite Numbers

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


Prime NumbersComposite Numbers
It deserve to only be split by 1 and also itself, thus have actually only 2 factors.It has more than two components (1 and also 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 two or much more numbers
Example: 5 has determinants are 1 and 5Example: 4 has components are 1, 2 and 4
