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

Apply this formula for all numbers.

Step1:

LCM(839, 681) = 571359

GCD(839, 681) = ( 839 x 681 ) / 571359

= 839 / 681

= 839

Step2:

LCM(1, 636) = 636

GCD(1, 636) = ( 1 x 636 ) / 636

= 1 / 636

= 1

Step3:

LCM(1, 861) = 861

GCD(1, 861) = ( 1 x 861 ) / 861

= 1 / 861

= 1

So, Greatest Common Divisor of 839, 681, 636, 861 is 1
