  • This theorem is the foundation for understanding prime factorization
  • The uniqueness of prime factorization means there is only one way to write a composite number as a product of primes
2

Applications of Fundamental Theorem of Arithmetic

  • Finding HCF: Product of lowest powers of common prime factors
  • Finding LCM: Product of highest powers of all prime factors
  • Determining whether a fraction is terminating or non-terminating
3

Revisiting Irrational Numbers

  • Irrational numbers cannot be expressed in the form p/q where p, q are integers and q ≠ 0
  • √p is irrational if p is a prime number
  • Proof technique: Contradiction method is used
