Given numbers are 779, 198, 228, 428

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

Apply this formula for all numbers.

Step1:

LCM(779, 198) = 154242

GCD(779, 198) = ( 779 x 198 ) / 154242

= 779 / 198

= 779

Step2:

LCM(1, 228) = 228

GCD(1, 228) = ( 1 x 228 ) / 228

= 1 / 228

= 1

Step3:

LCM(1, 428) = 428

GCD(1, 428) = ( 1 x 428 ) / 428

= 1 / 428

= 1

So, Greatest Common Divisor of 779, 198, 228, 428 is 1
