Finding GCD of 639, 563, 191 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(639, 563) = 359757

GCD(639, 563) = ( 639 x 563 ) / 359757

GCD(639, 563) = 359757 / 359757

GCD(639, 563) = 1


Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 191

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

LCM(1, 191) = 191

GCD(1, 191) = ( 1 x 191 ) / 191

GCD(1, 191) = 191 / 191

GCD(1, 191) = 1

GCD of 639, 563, 191 is 1
