The notes provide complete coverage of the topic, including:

  • Definition of prime numbers

  • Composite numbers

  • Prime factorisation methods

  • Divisibility tests

  • Multiples and factors

  • Highest Common Factor (HCF)

  • Least Common Multiple (LCM)

  • Fundamental Theorem of Arithmetic

  • Co-prime numbers

  • Properties of prime numbers

  • Number Theory applications

  • Olympiad-level practice questions
