Given numbers are 644, 681, 815, 589

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

Apply this formula for all numbers.

Step1:

LCM(644, 681) = 438564

GCD(644, 681) = ( 644 x 681 ) / 438564

= 644 / 681

= 644

Step2:

LCM(1, 815) = 815

GCD(1, 815) = ( 1 x 815 ) / 815

= 1 / 815

= 1

Step3:

LCM(1, 589) = 589

GCD(1, 589) = ( 1 x 589 ) / 589

= 1 / 589

= 1

So, Greatest Common Divisor of 644, 681, 815, 589 is 1
