The list of prime factors of all numbers are

Prime factors of 497 are 7 x 71

Prime factors of 645 are 3 x 5 x 43

Prime factors of 271 are 271

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

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

Given numbers are 497, 645, 271, 256

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

Apply this formula for all numbers.

Step1:

LCM(497, 645) = 320565

GCD(497, 645) = ( 497 x 645 ) / 320565

= 497 / 645

= 497

Step2:

LCM(1, 271) = 271

GCD(1, 271) = ( 1 x 271 ) / 271

= 1 / 271

= 1

Step3:

LCM(1, 256) = 256

GCD(1, 256) = ( 1 x 256 ) / 256

= 1 / 256

= 1

So, Greatest Common Divisor of 497, 645, 271, 256 is 1
