In Mathematics, composite numbers space numbers that have an ext than 2 factors. These numbers are also called composites. Composite number are just the the contrary of prime number which have only two factors, i.e. 1 and the number itself.  

All the organic numbers which room not prime numbers are composite numbers together they have the right to be split by an ext than 2 numbers. Because that example, 6 is a composite number due to the fact that it is divisible by 1, 2, 3 and even by 6.

In this article, we will discover the list of composite numbers, smallest composite number, strange composite numbers follow me examples.

What space Composite number in Maths?

The integers which have the right to be generated by multiply the two smallest positive integers and contain at the very least one divisor other than the number ‘1’ and also itself are known as composite numbers. This numbers always have an ext than 2 factors.

Fact: any even number i beg your pardon is better than 2 is a composite number.

Examples that Composite Numbers

The examples of composite numbers are 6, 14, 25, 30, 52, etc.

There are a variety of composite numbers we deserve to list the end of a collection of organic numbers indigenous 1 to 1000 or more. Let united state see the list of composite numbers in the next section.

Properties of Composite Numbers

The nature of composite number are straightforward to remember.

Composite numbers room evenly divisible by your factorsEach composite number will encompass at the very least one prime number as its factorComposite numbers are divisible by various other composite number also

List that Composite Numbers

Here is the list of composite numbers from 1 to 100 in Maths. Students deserve to keep a note of this and also try to create the numbers past 100 because that practice, such composites native 1 come 200 or till 500.

Composite numbers 1 to 200

The confident integers having more than two components are composite numbers. The list of Composite numbers from 1 come 200 room 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.

Is 0 a Composite Number?

Zero (0) is considered as neither prime nor a composite number since it do not have any type of factors.  

How to uncover the Composite Number?

The actions to find whether a provided number is prime or composite:

Find all the determinants of the optimistic integerA number is claimed to be element if it has actually only 2 factors, 1 and also itselfIf the number has more than 2 factors, climate it is a composite
Example: discover if 14 is a composite number.Let us uncover the determinants of 14.14÷1 = 1414÷2 = 714÷7 = 214÷14 = 1

As we deserve to see, the factors of 14 room 1,2,7 and also 14, so it is a composite number.


Types of Composite Numbers

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

Odd Composite number or Composite weird NumbersEven Composite number or Composite even Numbers

Odd Composite Numbers

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

Even Composite Numbers

All the even integers which space 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 that 1 is 1. The hopeful integers 2 and also 3 are prime numbers due to the fact that it have the right to be split by only two factors, one and also itself. Thus 2 and 3 space not composite.

But in the case of number 4, we have an ext than 2 factors. The divisors the 4 space 1,2,4. So this number satisfies the problem of a composite number as stated above. After ~ 4, 6 is the next composite positive integer, i beg your pardon has components 1, 2, 3 and 6.

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


Important Notes:Smallest Composite Number = 4Smallest prime Number = 2Smallest odd Composite Number = 9Two-digit smallest Composite Number = 10

Difference between Prime and Composite Numbers

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


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