Given numbers are 639, 395, 317, 606

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(639, 395) = 252405

GCD(639, 395) = ( 639 x 395 ) / 252405

= 639 / 395

= 639

Step2:

LCM(1, 317) = 317

GCD(1, 317) = ( 1 x 317 ) / 317

= 1 / 317

= 1

Step3:

LCM(1, 606) = 606

GCD(1, 606) = ( 1 x 606 ) / 606

= 1 / 606

= 1

So, Greatest Common Divisor of 639, 395, 317, 606 is 1
