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.
