Given numbers are 687, 729, 284, 621

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

Apply this formula for all numbers.

Step1:

LCM(687, 729) = 166941

GCD(687, 729) = ( 687 x 729 ) / 166941

= 687 / 729

= 687

Step2:

LCM(3, 284) = 852

GCD(3, 284) = ( 3 x 284 ) / 852

= 3 / 284

= 3

Step3:

LCM(1, 621) = 621

GCD(1, 621) = ( 1 x 621 ) / 621

= 1 / 621

= 1

So, Greatest Common Divisor of 687, 729, 284, 621 is 1
