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

Apply this formula for all numbers.

Step1:

LCM(930, 438) = 67890

GCD(930, 438) = ( 930 x 438 ) / 67890

= 930 / 438

= 930

Step2:

LCM(6, 189) = 378

GCD(6, 189) = ( 6 x 189 ) / 378

= 6 / 189

= 6

Step3:

LCM(3, 621) = 621

GCD(3, 621) = ( 3 x 621 ) / 621

= 3 / 621

= 3

So, Greatest Common Divisor of 930, 438, 189, 621 is 3
