Given numbers are 489, 173, 391, 692

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

Apply this formula for all numbers.

Step1:

LCM(489, 173) = 84597

GCD(489, 173) = ( 489 x 173 ) / 84597

= 489 / 173

= 489

Step2:

LCM(1, 391) = 391

GCD(1, 391) = ( 1 x 391 ) / 391

= 1 / 391

= 1

Step3:

LCM(1, 692) = 692

GCD(1, 692) = ( 1 x 692 ) / 692

= 1 / 692

= 1

So, Greatest Common Divisor of 489, 173, 391, 692 is 1
