Given numbers are 171, 221, 192, 345

The list of prime factors of all numbers are

Prime factors of 171 are 3 x 3 x 19

Prime factors of 221 are 13 x 17

Prime factors of 192 are 2 x 2 x 2 x 2 x 2 x 2 x 3

Prime factors of 345 are 3 x 5 x 23

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

Given numbers are 171, 221, 192, 345

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

Apply this formula for all numbers.

Step1:

LCM(171, 221) = 37791

GCD(171, 221) = ( 171 x 221 ) / 37791

= 171 / 221

= 171

Step2:

LCM(1, 192) = 192

GCD(1, 192) = ( 1 x 192 ) / 192

= 1 / 192

= 1

Step3:

LCM(1, 345) = 345

GCD(1, 345) = ( 1 x 345 ) / 345

= 1 / 345

= 1

So, Greatest Common Divisor of 171, 221, 192, 345 is 1
