Introduction to Composite Numbers
A positive integer that can be generated by multiplying two smaller positive integers is a composite number. All composite numbers can be written as the product of two or more primes. For example, an integer 21 is a composite number as it is the product of the two smaller integers 3 and 7.

According to basic Math, composite numbers are those numbers that have more than two factors present. The composite numbers or what is also commonly called the composites are the opposite of prime numbers which consists of only two factors and no more than that. When we say two factors there will be 1 and the other number present. All those numbers that are not prime numbers will be categorized as composite numbers. For you to better understand composite numbers and how they are found, here is a List of Composite Numbers from 1 to 100 via Vedantu that you can access and learn more about. This helps you to understand the composite numbers and their purposes in various mathematical equations.
Properties of Composite Numbers That Distinguish Them From Other Numbers:
Composite numbers are only those numbers that have more than two factors.
Composite numbers are also considered to be evenly divisible by the set of factors.
It is seen that each of the composite numbers is a factor of itself apart from 1 being the common factor.
The smallest of all composite numbers is 4 as it is divisible by 1, 2, and 4.
Each of the composite numbers will consist of at least two prime numbers that act as its factors. For example, if you check the composite number 10 it will have 2 and 5 as the prime numbers where the product of both will provide 10.
FAQs on List of Composite Numbers from 1 to 100
1. What are Composite Numbers?
Composite numbers can be defined in Math as the whole numbers that have more than two factors. Composite numbers are not prime, since they are divisible by more than two numbers.
2. What is the Smallest Odd Composite Number and Smallest Even Composite Number?
The smallest odd composite number is 9 and the smallest even composite number is 4.
3. Explain Why 0 and 1 are Neither Prime Nor Composite.
0 and 1 are neither composite nor prime. They are too distinctive because they reflect nothingness (zero) and wholeness (one), so there is no sense in the concept of having factors for 0 and 1. For instance, all even numbers are divisible by 2, and so composite numbers are all even numbers greater than 2.
4. Are 2 and 9 a composite number?
In the first case that is in the case of the number 2, it is not considered to be a composite number as there are two factors that are divisible with the number 2 which are 1 and 2. Hence the number 2 will not be considered as a composite number rather it will be considered as a prime number. On the other hand, number 9 has a total of 3 factors that it is divisible through. These numbers are 1,3 and 9. As it consists of more than two factors being divisible it is hence considered to be a composite number.
5. What is the difference between prime numbers and composite numbers in mathematics?
The difference between the prime numbers and the composite numbers can be provided as follows:
Prime Numbers | Composite Numbers |
Prime numbers can only be divided by the factor 1 and the other number being itself hence has only two factors being divisible. | Composite numbers on the other hand have more than two factors through which it can be divisible. |
It can only be mentioned as a product of two numbers and no more than that. | It can be represented as the product of two or more numbers. |
Example: 2 has two factors divisible such as 1 and 2. | Example: 9 has a total of three factors as 1, 3, and 9. |
