Given numbers are 639, 284, 814, 139

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, 814) = 57794

GCD(71, 814) = ( 71 x 814 ) / 57794

= 71 / 814

= 71

Step3:

LCM(1, 139) = 139

GCD(1, 139) = ( 1 x 139 ) / 139

= 1 / 139

= 1

So, Greatest Common Divisor of 639, 284, 814, 139 is 1
