Given numbers are 170, 221, 351, 230

The list of prime factors of all numbers are

Prime factors of 170 are 2 x 5 x 17

Prime factors of 221 are 13 x 17

Prime factors of 351 are 3 x 3 x 3 x 13

Prime factors of 230 are 2 x 5 x 23

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

Given numbers are 170, 221, 351, 230

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

Apply this formula for all numbers.

Step1:

LCM(170, 221) = 2210

GCD(170, 221) = ( 170 x 221 ) / 2210

= 170 / 221

= 170

Step2:

LCM(17, 351) = 5967

GCD(17, 351) = ( 17 x 351 ) / 5967

= 17 / 351

= 17

Step3:

LCM(1, 230) = 230

GCD(1, 230) = ( 1 x 230 ) / 230

= 1 / 230

= 1

So, Greatest Common Divisor of 170, 221, 351, 230 is 1
