Given numbers are 639, 284, 531, 310

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

Apply this formula for all numbers.

Step1:

LCM(639, 284) = 2556

GCD(639, 284) = ( 639 x 284 ) / 2556

= 639 / 284

= 639

Step2:

LCM(71, 531) = 37701

GCD(71, 531) = ( 71 x 531 ) / 37701

= 71 / 531

= 71

Step3:

LCM(1, 310) = 310

GCD(1, 310) = ( 1 x 310 ) / 310

= 1 / 310

= 1

So, Greatest Common Divisor of 639, 284, 531, 310 is 1
