Given numbers are 170, 258, 206, 957

The list of prime factors of all numbers are

Prime factors of 170 are 2 x 5 x 17

Prime factors of 258 are 2 x 3 x 43

Prime factors of 206 are 2 x 103

Prime factors of 957 are 3 x 11 x 29

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

Given numbers are 170, 258, 206, 957

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

Apply this formula for all numbers.

Step1:

LCM(170, 258) = 21930

GCD(170, 258) = ( 170 x 258 ) / 21930

= 170 / 258

= 170

Step2:

LCM(2, 206) = 206

GCD(2, 206) = ( 2 x 206 ) / 206

= 2 / 206

= 2

Step3:

LCM(2, 957) = 1914

GCD(2, 957) = ( 2 x 957 ) / 1914

= 2 / 957

= 2

So, Greatest Common Divisor of 170, 258, 206, 957 is 1
