Understanding Prime Numbers

What are prime numbers? | Year 5 Mathematics

  • Definition of Prime Numbers: Prime numbers are unique numbers greater than 1 that have only two factors, which are themselves and 1.
  • Examples:
    • For instance, 19 is a prime number since it can only be divided evenly by 1 and 19.
    • On the other hand, 9 is not a prime number because it can be divided by 3 as well as 1 and 9.
  • Prime Numbers Below 20: The prime numbers less than 20 include 2, 3, 5, 7, 11, 13, 17, and 19.
  • Special Note: The number 1 is not considered a prime number as it only has one factor.
