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
