Given numbers are 681, 319, 861, 389

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

Apply this formula for all numbers.

Step1:

LCM(681, 319) = 217239

GCD(681, 319) = ( 681 x 319 ) / 217239

= 681 / 319

= 681

Step2:

LCM(1, 861) = 861

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

= 1 / 861

= 1

Step3:

LCM(1, 389) = 389

GCD(1, 389) = ( 1 x 389 ) / 389

= 1 / 389

= 1

So, Greatest Common Divisor of 681, 319, 861, 389 is 1
