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

All the organic numbers which room not prime numbers space composite numbers as they deserve to be separated by more than 2 numbers. Because that example, 6 is a composite number since it is divisible by 1, 2, 3 and even through 6.

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

What room Composite number in Maths?

Definition 1: In Mathematics, composite numbers room numbers that have much more than 2 factors.

Definition 2: The number which have the right to be produced by multiply the two smallest optimistic integers and contain at least one divisor other than the number ‘1’ and also itself are recognized as composite numbers. These numbers always have an ext than two factors.

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

Is 0 a Composite Number?

Zero (0) is thought about as neither prime nor a composite number since it does no have any kind of factors.

Composite numbers Examples

The instances 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 have the right to see the composite numbers have much more than 2 factors. There room a number of composite numbers we deserve to list out of a set of organic numbers indigenous 1 come 1000 or more. Let united state see the perform of composite numbers in the following section.

Properties the Composite Numbers

The properties of composite numbers are easy to remember.

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

List of Composite Numbers

Here is the list of composite numbers from 1 come 100 in Maths. Students deserve to keep a note of this and also also shot to create the numbers beyond 100 for practice, together composites native 1 to 200 or it rotates 500.

Composite numbers 1 to 200

The hopeful integers having an ext than two factors are composite numbers. The perform of Composite numbers from 1 to 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 also 198.

How to discover the Composite Number?

The measures to uncover whether a given number is prime or composite:

Find every the factors of the positive integerA number is stated to be prime if it has only 2 factors, 1 and also itselfIf the number has much 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 have the right to see, the determinants of 14 are 1,2,7 and also 14, so that is a composite number.


Types that Composite Numbers

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

Odd Composite numbers 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 room 9, 15, 21, 25, 27, 31, etc.

Even Composite Numbers

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

Smallest Composite Number

4 is the smallest composite number.

Why?

1 is not a composite number since the sole divisor the 1 is 1. The optimistic integers 2 and 3 space prime numbers due to the fact that it have the right to be separated by only two factors, one and also itself. Hence 2 and also 3 room not composite.

But in the case of number 4, we have much more than 2 factors. The divisors that 4 room 1,2,4. So this number satisfies the problem of a composite number as discussed above. After ~ 4, 6 is the following composite hopeful 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 Composite Numbers

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


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