Given numbers are 459, 256, 930, 221

The list of prime factors of all numbers are

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

Prime factors of 256 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2

Prime factors of 930 are 2 x 3 x 5 x 31

Prime factors of 221 are 13 x 17

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

Given numbers are 459, 256, 930, 221

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

Apply this formula for all numbers.

Step1:

LCM(459, 256) = 117504

GCD(459, 256) = ( 459 x 256 ) / 117504

= 459 / 256

= 459

Step2:

LCM(1, 930) = 930

GCD(1, 930) = ( 1 x 930 ) / 930

= 1 / 930

= 1

Step3:

LCM(1, 221) = 221

GCD(1, 221) = ( 1 x 221 ) / 221

= 1 / 221

= 1

So, Greatest Common Divisor of 459, 256, 930, 221 is 1
