Given numbers are 459, 447, 165, 161

The list of prime factors of all numbers are

Prime factors of 459 are 3 x 3 x 3 x 17

Prime factors of 447 are 3 x 149

Prime factors of 165 are 3 x 5 x 11

Prime factors of 161 are 7 x 23

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

Given numbers are 459, 447, 165, 161

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

Apply this formula for all numbers.

Step1:

LCM(459, 447) = 68391

GCD(459, 447) = ( 459 x 447 ) / 68391

= 459 / 447

= 459

Step2:

LCM(3, 165) = 165

GCD(3, 165) = ( 3 x 165 ) / 165

= 3 / 165

= 3

Step3:

LCM(3, 161) = 483

GCD(3, 161) = ( 3 x 161 ) / 483

= 3 / 161

= 3

So, Greatest Common Divisor of 459, 447, 165, 161 is 1
