Given numbers are 871, 663, 171, 479

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

Apply this formula for all numbers.

Step1:

LCM(871, 663) = 44421

GCD(871, 663) = ( 871 x 663 ) / 44421

= 871 / 663

= 871

Step2:

LCM(13, 171) = 2223

GCD(13, 171) = ( 13 x 171 ) / 2223

= 13 / 171

= 13

Step3:

LCM(1, 479) = 479

GCD(1, 479) = ( 1 x 479 ) / 479

= 1 / 479

= 1

So, Greatest Common Divisor of 871, 663, 171, 479 is 1
