Given numbers are 681, 387, 706, 289

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

Apply this formula for all numbers.

Step1:

LCM(681, 387) = 87849

GCD(681, 387) = ( 681 x 387 ) / 87849

= 681 / 387

= 681

Step2:

LCM(3, 706) = 2118

GCD(3, 706) = ( 3 x 706 ) / 2118

= 3 / 706

= 3

Step3:

LCM(1, 289) = 289

GCD(1, 289) = ( 1 x 289 ) / 289

= 1 / 289

= 1

So, Greatest Common Divisor of 681, 387, 706, 289 is 1
