Given numbers are 355, 357, 189, 361

The list of prime factors of all numbers are

Prime factors of 355 are 5 x 71

Prime factors of 357 are 3 x 7 x 17

Prime factors of 189 are 3 x 3 x 3 x 7

Prime factors of 361 are 19 x 19

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

Given numbers are 355, 357, 189, 361

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

Apply this formula for all numbers.

Step1:

LCM(355, 357) = 126735

GCD(355, 357) = ( 355 x 357 ) / 126735

= 355 / 357

= 355

Step2:

LCM(1, 189) = 189

GCD(1, 189) = ( 1 x 189 ) / 189

= 1 / 189

= 1

Step3:

LCM(1, 361) = 361

GCD(1, 361) = ( 1 x 361 ) / 361

= 1 / 361

= 1

So, Greatest Common Divisor of 355, 357, 189, 361 is 1
