Given numbers are 389, 609, 687, 908

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

Apply this formula for all numbers.

Step1:

LCM(389, 609) = 236901

GCD(389, 609) = ( 389 x 609 ) / 236901

= 389 / 609

= 389

Step2:

LCM(1, 687) = 687

GCD(1, 687) = ( 1 x 687 ) / 687

= 1 / 687

= 1

Step3:

LCM(1, 908) = 908

GCD(1, 908) = ( 1 x 908 ) / 908

= 1 / 908

= 1

So, Greatest Common Divisor of 389, 609, 687, 908 is 1
