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

Apply this formula for all numbers.

Step1:

LCM(428, 256) = 27392

GCD(428, 256) = ( 428 x 256 ) / 27392

= 428 / 256

= 428

Step2:

LCM(4, 199) = 796

GCD(4, 199) = ( 4 x 199 ) / 796

= 4 / 199

= 4

So, Greatest Common Divisor of 428, 256, 199 is 1
