Given numbers are 817, 871, 257, 939

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

Apply this formula for all numbers.

Step1:

LCM(817, 871) = 711607

GCD(817, 871) = ( 817 x 871 ) / 711607

= 817 / 871

= 817

Step2:

LCM(1, 257) = 257

GCD(1, 257) = ( 1 x 257 ) / 257

= 1 / 257

= 1

Step3:

LCM(1, 939) = 939

GCD(1, 939) = ( 1 x 939 ) / 939

= 1 / 939

= 1

So, Greatest Common Divisor of 817, 871, 257, 939 is 1
