Key Concepts of Prime and Composite Numbers
Understanding prime and composite numbers is foundational in math. Prime numbers have exactly two distinct factors like 2, 3, 5, and 7. Composite numbers have more than two factors and can be divided into prime factors.
Definition of Prime Numbers
A prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself. The smallest prime number is 2, which is also the only even prime number. Examples of prime numbers include 3, 5, 7, and 11. These numbers cannot be formed by multiplying two smaller natural numbers, making them unique in their factorization. Prime numbers play a crucial role in number theory and are essential for understanding composite numbers and their properties.
Definition of Composite Numbers
A composite number is a positive integer greater than 1 that has more than two distinct factors. Unlike prime numbers, composite numbers can be divided evenly by numbers other than 1 and themselves. Examples of composite numbers include 4, 6, 8, and 9. These numbers are essential in math as they can be factored into smaller prime numbers. All even numbers greater than 2 are composite, and most natural numbers fall into this category, making them fundamental for understanding number relationships.
Classifying Numbers as Prime or Composite
Classifying numbers as prime or composite involves identifying their factors. A prime number has exactly two distinct factors: 1 and itself. For example, 5 is prime because its only factors are 1 and 5. A composite number, however, has more than two factors. For instance, 6 is composite because it can be divided by 1, 2, 3, and 6. Understanding factors and multiples is key to this classification. Worksheets often include exercises where students list factors to determine if a number is prime or composite, helping them master this essential math skill.
