Given numbers are 428, 170, 238, 417

The list of prime factors of all numbers are

Prime factors of 428 are 2 x 2 x 107

Prime factors of 170 are 2 x 5 x 17

Prime factors of 238 are 2 x 7 x 17

Prime factors of 417 are 3 x 139

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

Given numbers are 428, 170, 238, 417

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

Apply this formula for all numbers.

Step1:

LCM(428, 170) = 36380

GCD(428, 170) = ( 428 x 170 ) / 36380

= 428 / 170

= 428

Step2:

LCM(2, 238) = 238

GCD(2, 238) = ( 2 x 238 ) / 238

= 2 / 238

= 2

Step3:

LCM(2, 417) = 834

GCD(2, 417) = ( 2 x 417 ) / 834

= 2 / 417

= 2

So, Greatest Common Divisor of 428, 170, 238, 417 is 1
