Given numbers are 398, 854, 457, 838

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

Apply this formula for all numbers.

Step1:

LCM(398, 854) = 169946

GCD(398, 854) = ( 398 x 854 ) / 169946

= 398 / 854

= 398

Step2:

LCM(2, 457) = 914

GCD(2, 457) = ( 2 x 457 ) / 914

= 2 / 457

= 2

Step3:

LCM(1, 838) = 838

GCD(1, 838) = ( 1 x 838 ) / 838

= 1 / 838

= 1

So, Greatest Common Divisor of 398, 854, 457, 838 is 1
