Given numbers are 689, 585, 397, 128

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

Apply this formula for all numbers.

Step1:

LCM(689, 585) = 31005

GCD(689, 585) = ( 689 x 585 ) / 31005

= 689 / 585

= 689

Step2:

LCM(13, 397) = 5161

GCD(13, 397) = ( 13 x 397 ) / 5161

= 13 / 397

= 13

Step3:

LCM(1, 128) = 128

GCD(1, 128) = ( 1 x 128 ) / 128

= 1 / 128

= 1

So, Greatest Common Divisor of 689, 585, 397, 128 is 1
