Given numbers are 170, 478, 842, 867

The list of prime factors of all numbers are

Prime factors of 170 are 2 x 5 x 17

Prime factors of 478 are 2 x 239

Prime factors of 842 are 2 x 421

Prime factors of 867 are 3 x 17 x 17

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 170, 478, 842, 867

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

Apply this formula for all numbers.

Step1:

LCM(170, 478) = 40630

GCD(170, 478) = ( 170 x 478 ) / 40630

= 170 / 478

= 170

Step2:

LCM(2, 842) = 842

GCD(2, 842) = ( 2 x 842 ) / 842

= 2 / 842

= 2

Step3:

LCM(2, 867) = 1734

GCD(2, 867) = ( 2 x 867 ) / 1734

= 2 / 867

= 2

So, Greatest Common Divisor of 170, 478, 842, 867 is 1
