Given numbers are 285, 389, 111, 403

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

Apply this formula for all numbers.

Step1:

LCM(285, 389) = 110865

GCD(285, 389) = ( 285 x 389 ) / 110865

= 285 / 389

= 285

Step2:

LCM(1, 111) = 111

GCD(1, 111) = ( 1 x 111 ) / 111

= 1 / 111

= 1

Step3:

LCM(1, 403) = 403

GCD(1, 403) = ( 1 x 403 ) / 403

= 1 / 403

= 1

So, Greatest Common Divisor of 285, 389, 111, 403 is 1
