Given numbers are 638, 511, 256, 468

The list of prime factors of all numbers are

Prime factors of 638 are 2 x 11 x 29

Prime factors of 511 are 7 x 73

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

Prime factors of 468 are 2 x 2 x 3 x 3 x 13

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

Given numbers are 638, 511, 256, 468

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

Apply this formula for all numbers.

Step1:

LCM(638, 511) = 326018

GCD(638, 511) = ( 638 x 511 ) / 326018

= 638 / 511

= 638

Step2:

LCM(1, 256) = 256

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

= 1 / 256

= 1

Step3:

LCM(1, 468) = 468

GCD(1, 468) = ( 1 x 468 ) / 468

= 1 / 468

= 1

So, Greatest Common Divisor of 638, 511, 256, 468 is 1
