Given numbers are 391, 322, 785, 681

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

Apply this formula for all numbers.

Step1:

LCM(391, 322) = 5474

GCD(391, 322) = ( 391 x 322 ) / 5474

= 391 / 322

= 391

Step2:

LCM(23, 785) = 18055

GCD(23, 785) = ( 23 x 785 ) / 18055

= 23 / 785

= 23

Step3:

LCM(1, 681) = 681

GCD(1, 681) = ( 1 x 681 ) / 681

= 1 / 681

= 1

So, Greatest Common Divisor of 391, 322, 785, 681 is 1
