# Composite numbers from 1 to 100

Learn and know the total number of composite numbers from 1 to 100. Not only the total number of composite numbers, I will also list the composite numbers which are between 1 to 100. Before listing them first we will start learning the definition of composite numbers. Do you know what does a composite number mean? For this, the answer will be given in definition of composite number.

What is a composite number? And how to define it.  A composite number can be defined as “a positive number which has a minimum of three factors (more than 2) is called as a composite number. One more definition, we can give as “a number which is not a prime number is called a composite number.

## List of composite numbers from 1 to 100:

We know what is a composite number and now we will write all the composite numbers from 1 to 100. After writing we will count and see how many composite numbers are present in between 1 to 100.

 1 – 10 4, 6, 8, 9, 10 11 – 20 12, 14, 15, 16, 18, 20 21 – 30 21, 22, 24, 25, 26, 27, 28, 30 31 -40 32, 33, 34, 35, 36, 38, 39, 40 41 – 50 42,44,45,46,48,49,50 51 – 60 51, 52, 54, 55, 56, 57, 58, 60 61 – 70 62, 63, 64, 65, 66, 68, 69, 70 71 – 80 72, 74, 75, 76, 77, 78, 80 81 – 90 81, 82, 84, 85, 86, 87, 88, 90 91 – 100 91, 92, 93, 94, 95, 96, 98, 99, 100

From the above given list, we can notice the following things:

There are totally twenty five odd and forty nine even composite numbers from 1 to 100.

Finally, we observed that there are totally 74 composite numbers from 1 to 100. Hope that I have given sufficient information on composite numbers.
