Given numbers are 428, 634, 192, 115

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

Apply this formula for all numbers.

Step1:

LCM(428, 634) = 135676

GCD(428, 634) = ( 428 x 634 ) / 135676

= 428 / 634

= 428

Step2:

LCM(2, 192) = 192

GCD(2, 192) = ( 2 x 192 ) / 192

= 2 / 192

= 2

Step3:

LCM(2, 115) = 230

GCD(2, 115) = ( 2 x 115 ) / 230

= 2 / 115

= 2

So, Greatest Common Divisor of 428, 634, 192, 115 is 1
