Given numbers are 189, 257, 428, 294

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

Apply this formula for all numbers.

Step1:

LCM(189, 257) = 48573

GCD(189, 257) = ( 189 x 257 ) / 48573

= 189 / 257

= 189

Step2:

LCM(1, 428) = 428

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

= 1 / 428

= 1

Step3:

LCM(1, 294) = 294

GCD(1, 294) = ( 1 x 294 ) / 294

= 1 / 294

= 1

So, Greatest Common Divisor of 189, 257, 428, 294 is 1
