Given numbers are 681, 438, 97, 819

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

Apply this formula for all numbers.

Step1:

LCM(681, 438) = 99426

GCD(681, 438) = ( 681 x 438 ) / 99426

= 681 / 438

= 681

Step2:

LCM(3, 97) = 291

GCD(3, 97) = ( 3 x 97 ) / 291

= 3 / 97

= 3

Step3:

LCM(1, 819) = 819

GCD(1, 819) = ( 1 x 819 ) / 819

= 1 / 819

= 1

So, Greatest Common Divisor of 681, 438, 97, 819 is 1
