Given numbers are 398, 256, 571, 875

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

Apply this formula for all numbers.

Step1:

LCM(398, 256) = 50944

GCD(398, 256) = ( 398 x 256 ) / 50944

= 398 / 256

= 398

Step2:

LCM(2, 571) = 1142

GCD(2, 571) = ( 2 x 571 ) / 1142

= 2 / 571

= 2

Step3:

LCM(1, 875) = 875

GCD(1, 875) = ( 1 x 875 ) / 875

= 1 / 875

= 1

So, Greatest Common Divisor of 398, 256, 571, 875 is 1
