Given numbers are 398, 870, 539, 819

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

Apply this formula for all numbers.

Step1:

LCM(398, 870) = 173130

GCD(398, 870) = ( 398 x 870 ) / 173130

= 398 / 870

= 398

Step2:

LCM(2, 539) = 1078

GCD(2, 539) = ( 2 x 539 ) / 1078

= 2 / 539

= 2

Step3:

LCM(1, 819) = 819

GCD(1, 819) = ( 1 x 819 ) / 819

= 1 / 819

= 1

So, Greatest Common Divisor of 398, 870, 539, 819 is 1
