Given numbers are 424, 720, 928, 389

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

Apply this formula for all numbers.

Step1:

LCM(424, 720) = 38160

GCD(424, 720) = ( 424 x 720 ) / 38160

= 424 / 720

= 424

Step2:

LCM(8, 928) = 928

GCD(8, 928) = ( 8 x 928 ) / 928

= 8 / 928

= 8

Step3:

LCM(8, 389) = 3112

GCD(8, 389) = ( 8 x 389 ) / 3112

= 8 / 389

= 8

So, Greatest Common Divisor of 424, 720, 928, 389 is 1
