Given numbers are 285, 391, 559, 277

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

Apply this formula for all numbers.

Step1:

LCM(285, 391) = 111435

GCD(285, 391) = ( 285 x 391 ) / 111435

= 285 / 391

= 285

Step2:

LCM(1, 559) = 559

GCD(1, 559) = ( 1 x 559 ) / 559

= 1 / 559

= 1

Step3:

LCM(1, 277) = 277

GCD(1, 277) = ( 1 x 277 ) / 277

= 1 / 277

= 1

So, Greatest Common Divisor of 285, 391, 559, 277 is 1
