The examples of even composite numbers are 4, 6, 8, 10, and more. Even Composite NumbersĮven composite numbers include all even integers that are not prime numbers. The examples of odd composite numbers are 9, 15, 21, and more. Students can understand the concept of prime numbers from this list and create a list beyond 100 for practice.Īll odd numbers greater than 1 that are not prime are odd composite numbers. Here is a list of prime numbers from 1 to 100.
Every composite number can be factorized into prime factors. Two prime numbers are coprime to one another. Every positive integer that is even and greater than 2 can be written as the sum of two prime numbers. Every number that is greater than 1 can be divided by at least one prime number. Each prime number is a factor of itself. The following are some properties of prime numbers: For example, 2 and 3, 4 and 5, 3 and 7, 4 and 9 are co-prime numbers. In other words, they are two consecutive prime numbers that have only one number between them.Ĭo-Prime Numbers Co-prime numbers are the two numbers that have only 1 as a common factor. For example, 3 and 5, 5 and 7, 11 and 13 are sets of twin prime numbers. Twin Primes The prime numbers whose difference is two are twin prime numbers. Largest Prime Number 2^(82,589,933) – 1 is the recent largest prime number. There are some interesting facts about prime numbers. We can also define a prime number as a number that is a positive integer and is not a product of any other two positive integers other than the number itself and 1. So, if n is a prime number, its factors will be 1 and n itself. It has exactly two factors, 1 and the number itself. Facts about prime and composite numbersĪ prime number is a positive integer. 
How to identify prime and composite numbers.Properties of prime and composite numbers.Difference between prime and composite numbers.In this article, we will learn the following: So, composite numbers are divisible by more than two numbers. All the natural numbers that are not prime numbers fall into the category of composite numbers. A prime number is always a natural number. Prime numbers are those that have just two factors, i.e. They are just the opposite of prime numbers.
While composite numbers are numbers with more than two factors. It is crucial to understand the difference between prime and composite numbers in Mathematics.
