Finding GCD of 22, 66, 72 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(22, 66) = 66
GCD(22, 66) = ( 22 x 66 ) / 66
GCD(22, 66) = 1452 / 66
GCD(22, 66) = 22
Step2:
Here we consider the GCD from the above i.e. 22 as first number and the next as 72
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(22, 72) = 792
GCD(22, 72) = ( 22 x 72 ) / 792
GCD(22, 72) = 1584 / 792
GCD(22, 72) = 2
GCD of 22, 66, 72 is 2
