Formula For HCF


HCF – The H.C.F of two or more than two numbers is the greatest numbers which divides each of them without any remainder. It also called Greatest Common Divisor (G.C.D.) or Greatest Common Measure (G.C.M.) 


  • Product of two numbers = Product of their H.C.F. and L.C.M
  • Co-primes: Two numbers are said to be co-primes if their H.C.F. is 1
  • HCM and LCM of fraction

           a. HCF = HCF of Numerator/LCM of Denominators
           b. LCM = LCM of Numerator/HCF of Denominators
