Composite Numbers From 1 to 100
The list of composite numbers 1 to 100 provides you with all the numbers that come from 1 to 100 that have more than two factors. Composite numbers are natural numbers that have more than two factors (1 and the number itself). In other words, if a number has factors other than 1 and the number itself, it is considered a composite number. Let us look at all the composite numbers 1 to 100 in this article and study them through a chart for a better understanding.
What are Composite Numbers From 1 to 100?
Composite numbers from 1 to 100 are natural numbers between 1 and 100 that have more than two factors (that is, they have factor(s) other than 1 and the number itself). We have a total of 74 such composite numbers between 1 and 100. Some of the composite numbers between 1 to 100 are 4, 6, 8, 9, 10, 12, 14, 15, etc. These numbers have factors other than 1 and the number itself. Let us see the factors of some of the composite numbers from 1 to 100.
- Factors of 4: 1, 2, 4
- Factors of 6: 1, 2, 3, 6
- Factors of 9: 1, 3, 9
- Factors of 10: 1, 2, 5, 10
All of the above numbers have more than two factors. So, they are all composite numbers and lie between 1 and 100. Let us go through the list of composite numbers from 1 to 100 in the next section.
List of Composite Numbers Between 1 to 100
There is a total of 74 composite numbers from 1 to 100.

All other numbers between 1 and 100 except these are prime numbers.
Odd Composite Numbers 1 to 100
Odd composite numbers mean all the odd numbers that are not prime. For example, 63, 55, 69, and so on. There are a total of 25 odd composite numbers from 1 to 100. The list of odd composite numbers 1 to 100 includes 9, 15, 21, 25, 27, 33, 35, 39, 45, 49, 51, 55, 57, 63, 65, 69, 75, 77, 81, 85, 87, 91, 93, 95, and 99.
Even Composite Numbers From 1 to 100
Even composite numbers are even numbers that have more than two factors. As we know, all even numbers except 2 are composite. So, all even numbers except 2 between 1 to 100 are composite numbers. So, the list of even composite numbers from 1 to 100 are 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36, 38, 40, 42, 44, 46, 48, 50, 52, 54, 56, 58, 60, 62, 64, 66, 68, 70,72, 74, 76, 78, 80, 82, 84, 86, 88, 90, 92, 94, 96, 98, and 100.
Composite Numbers From 1 to 100 Chart
The composite numbers 1 to 100 chart will help you to quickly check if a number is composite or prime. If a number is composite, then we can list down its factors by using the prime factorization method. For example, 10 is a composite number and its factors are 1, 2, 5, and 10. If a number is not composite, it means that the factors of that number are 1 and the number itself. For example, we can see that 29 is marked as a prime number in the chart given below, therefore we can say that 29 has 2 factors which are 1 and 29.
In the chart of composite numbers 1 to 100 given above, all the highlighted numbers in a darker shade of blue are composite numbers. For example, 4, 6, 8, 9, 10, and so on.
