Given numbers are 398, 669, 305, 191

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

Apply this formula for all numbers.

Step1:

LCM(398, 669) = 266262

GCD(398, 669) = ( 398 x 669 ) / 266262

= 398 / 669

= 398

Step2:

LCM(1, 305) = 305

GCD(1, 305) = ( 1 x 305 ) / 305

= 1 / 305

= 1

Step3:

LCM(1, 191) = 191

GCD(1, 191) = ( 1 x 191 ) / 191

= 1 / 191

= 1

So, Greatest Common Divisor of 398, 669, 305, 191 is 1
