Finding GCD of 45, 60, 27 using LCM Formula

Step1:

Let's calculate the GCD of first two numbers

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(45, 60) = 180

GCD(45, 60) = ( 45 x 60 ) / 180

GCD(45, 60) = 2700 / 180

GCD(45, 60) = 15


Step2:

Here we consider the GCD from the above i.e. 15 as first number and the next as 27

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(15, 27) = 135

GCD(15, 27) = ( 15 x 27 ) / 135

GCD(15, 27) = 405 / 135

GCD(15, 27) = 3

GCD of 45, 60, 27 is 3
