Prime and composite numbers are the two types of numbers, that differ based on the number of factors they have. A prime number is the one that has only two factors and a composite number has more than two factors. A factor is a value, that can divide a number or an expression evenly.
Here you will learn about prime and composite numbers, including what prime and composite numbers are and how to determine whether a number is prime or composite. Students will first learn about prime and composite numbers as a part of operations and algebraic thinking in 4 th grade.
To determine if a number is prime or composite, you have to determine if the number has any divisors other than 1 and itself. The divisibility rules are useful here, and can quickly show you if a number has a divisor on that list.

What are the prime and composite numbers? Prime numbers are those numbers which have only two factors 1 and the number itself. Composite numbers are those numbers which have more than two factors.
A Prime Number is: a whole number above 1 that cannot be made by multiplying other whole numbers. Example: 5 is a prime number. We cannot multiply other whole numbers (like 2, 3, 4, etc) to make 5. Example: 6 is not a prime number. 6 can be made by 2×3 so is NOT a prime number, it is a composite number.
Understand the relationship between prime and composite numbers; Explore patterns in number sequences; Build a foundation for more advanced topics like number theory and algebra; Educators can use these properties to create engaging activities, such as: Finding all factors of a given composite number; Exploring prime factorization
