Given numbers are 170, 865, 257, 134

The list of prime factors of all numbers are

Prime factors of 170 are 2 x 5 x 17

Prime factors of 865 are 5 x 173

Prime factors of 257 are 257

Prime factors of 134 are 2 x 67

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

Given numbers are 170, 865, 257, 134

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

Apply this formula for all numbers.

Step1:

LCM(170, 865) = 29410

GCD(170, 865) = ( 170 x 865 ) / 29410

= 170 / 865

= 170

Step2:

LCM(5, 257) = 1285

GCD(5, 257) = ( 5 x 257 ) / 1285

= 5 / 257

= 5

Step3:

LCM(1, 134) = 134

GCD(1, 134) = ( 1 x 134 ) / 134

= 1 / 134

= 1

So, Greatest Common Divisor of 170, 865, 257, 134 is 1
