Finding GCD of 68, 64, 66 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(68, 64) = 1088
GCD(68, 64) = ( 68 x 64 ) / 1088
GCD(68, 64) = 4352 / 1088
GCD(68, 64) = 4
Step2:
Here we consider the GCD from the above i.e. 4 as first number and the next as 66
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(4, 66) = 132
GCD(4, 66) = ( 4 x 66 ) / 132
GCD(4, 66) = 264 / 132
GCD(4, 66) = 2
GCD of 68, 64, 66 is 2
