Given numbers are 189, 477, 178, 392

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

Apply this formula for all numbers.

Step1:

LCM(189, 477) = 10017

GCD(189, 477) = ( 189 x 477 ) / 10017

= 189 / 477

= 189

Step2:

LCM(9, 178) = 1602

GCD(9, 178) = ( 9 x 178 ) / 1602

= 9 / 178

= 9

Step3:

LCM(1, 392) = 392

GCD(1, 392) = ( 1 x 392 ) / 392

= 1 / 392

= 1

So, Greatest Common Divisor of 189, 477, 178, 392 is 1
