H.C.F and L.C.M of Fractions

1. L.C.M of Fraction = L.C.M of Numerator / H.C.F of denominator
eg. LCM of 3/4 and 1/2 is
LCM of 3 and 1 / HCF of 4 and 2 = 3/2
2. H.C.F of Fraction = H.C.F of Numerator / L.C.M of denominator
eg. HCF of 3/4 and 1/2 is
HCF of 3 and 1 / LCM of 4 and 2 = 1/4

3. In case of LCM if single Remainder is given then first LCM of the numbers is calculated then subtract remainder from the LCM
