Prime And Composite Numbers 1 To 100 Chart
Introduction
Numbers are an integral part of our daily lives, and we use them in various ways. It is important to learn about different types of numbers and their properties. In this article, we will discuss prime and composite numbers from 1 to 100. We will also provide a chart to help you understand the concept better.
What are Prime Numbers?
Prime numbers are positive integers that have only two factors, 1 and the number itself. For example, 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, and 97 are prime numbers from 1 to 100.
What are Composite Numbers?
Composite numbers are positive integers that have more than two factors. In other words, they are not prime numbers. For example, 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, and 99 are composite numbers from 1 to 100.

How to Identify Prime and Composite Numbers?
To identify whether a number is prime or composite, you need to follow these steps:
- Divide the number by all the numbers less than or equal to its square root.
- If the number has a factor other than 1 and itself, it is a composite number.
- If the number does not have any factor other than 1 and itself, it is a prime number.
