Given numbers are 289, 523, 388, 728

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

Apply this formula for all numbers.

Step1:

LCM(289, 523) = 151147

GCD(289, 523) = ( 289 x 523 ) / 151147

= 289 / 523

= 289

Step2:

LCM(1, 388) = 388

GCD(1, 388) = ( 1 x 388 ) / 388

= 1 / 388

= 1

Step3:

LCM(1, 728) = 728

GCD(1, 728) = ( 1 x 728 ) / 728

= 1 / 728

= 1

So, Greatest Common Divisor of 289, 523, 388, 728 is 1
