Given numbers are 684, 660, 489, 928

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

Apply this formula for all numbers.

Step1:

LCM(684, 660) = 37620

GCD(684, 660) = ( 684 x 660 ) / 37620

= 684 / 660

= 684

Step2:

LCM(12, 489) = 1956

GCD(12, 489) = ( 12 x 489 ) / 1956

= 12 / 489

= 12

Step3:

LCM(3, 928) = 2784

GCD(3, 928) = ( 3 x 928 ) / 2784

= 3 / 928

= 3

So, Greatest Common Divisor of 684, 660, 489, 928 is 1
