HCF and LCM

Vedic Maths trick to find HCF and LCM.

Q1. Find LCM and HCF of 6/10,9/14,4/13,6/3

Formula to calculate LCM-

LCM = LCM of Numerator / HCF of Denominators

LCM of numerator i.e. 6 , 9 , 4 ,6 = 36

HCF of denominator i.e. 10 , 14 , 13 ,3 = 1

LCM = 36/1

Formula to calculate HCF-

HCF = HCF of Numerator / LCM of Denominators

LCM of denominator i.e. 10 , 14 , 13 ,3 = 2730

HCF of numerator i.e. 6 , 9 , 4 ,6 = 1

HCF = 1/2730


Q2. Find LCM and HCF of 0.56 , 0.6 , 1.5

Remove the decimal numbers - 56 , 60 , 150

LCM of 56 , 60 , 150 = 4200

and put the decimal point after two digits so lcm will be 42.00

HCF of 56 , 60 , 150 = 2

and put the decimal point after two digits so hcf will be 0.02
