Given numbers are 939, 489, 248, 689

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

Apply this formula for all numbers.

Step1:

LCM(939, 489) = 153057

GCD(939, 489) = ( 939 x 489 ) / 153057

= 939 / 489

= 939

Step2:

LCM(3, 248) = 744

GCD(3, 248) = ( 3 x 248 ) / 744

= 3 / 248

= 3

Step3:

LCM(1, 689) = 689

GCD(1, 689) = ( 1 x 689 ) / 689

= 1 / 689

= 1

So, Greatest Common Divisor of 939, 489, 248, 689 is 1
