Given numbers are 405, 255, 302, 161

The list of prime factors of all numbers are

Prime factors of 405 are 3 x 3 x 3 x 3 x 5

Prime factors of 255 are 3 x 5 x 17

Prime factors of 302 are 2 x 151

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 405, 255, 302, 161

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

Apply this formula for all numbers.

Step1:

LCM(405, 255) = 6885

GCD(405, 255) = ( 405 x 255 ) / 6885

= 405 / 255

= 405

Step2:

LCM(15, 302) = 4530

GCD(15, 302) = ( 15 x 302 ) / 4530

= 15 / 302

= 15

Step3:

LCM(1, 161) = 161

GCD(1, 161) = ( 1 x 161 ) / 161

= 1 / 161

= 1

So, Greatest Common Divisor of 405, 255, 302, 161 is 1
