Given numbers are 287, 861, 921, 386

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

Apply this formula for all numbers.

Step1:

LCM(287, 861) = 861

GCD(287, 861) = ( 287 x 861 ) / 861

= 287 / 861

= 287

Step2:

LCM(287, 921) = 264327

GCD(287, 921) = ( 287 x 921 ) / 264327

= 287 / 921

= 287

Step3:

LCM(1, 386) = 386

GCD(1, 386) = ( 1 x 386 ) / 386

= 1 / 386

= 1

So, Greatest Common Divisor of 287, 861, 921, 386 is 1
