Given numbers are 389, 478, 923, 255

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

Apply this formula for all numbers.

Step1:

LCM(389, 478) = 185942

GCD(389, 478) = ( 389 x 478 ) / 185942

= 389 / 478

= 389

Step2:

LCM(1, 923) = 923

GCD(1, 923) = ( 1 x 923 ) / 923

= 1 / 923

= 1

Step3:

LCM(1, 255) = 255

GCD(1, 255) = ( 1 x 255 ) / 255

= 1 / 255

= 1

So, Greatest Common Divisor of 389, 478, 923, 255 is 1
