Finding GCD of 618, 144, 28 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(618, 144) = 14832
GCD(618, 144) = ( 618 x 144 ) / 14832
GCD(618, 144) = 88992 / 14832
GCD(618, 144) = 6
Step2:
Here we consider the GCD from the above i.e. 6 as first number and the next as 28
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(6, 28) = 84
GCD(6, 28) = ( 6 x 28 ) / 84
GCD(6, 28) = 168 / 84
GCD(6, 28) = 2
GCD of 618, 144, 28 is 2
