Given numbers are 605, 873, 256, 648

The list of prime factors of all numbers are

Prime factors of 605 are 5 x 11 x 11

Prime factors of 873 are 3 x 3 x 97

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

Prime factors of 648 are 2 x 2 x 2 x 3 x 3 x 3 x 3

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

Given numbers are 605, 873, 256, 648

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

Apply this formula for all numbers.

Step1:

LCM(605, 873) = 528165

GCD(605, 873) = ( 605 x 873 ) / 528165

= 605 / 873

= 605

Step2:

LCM(1, 256) = 256

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

= 1 / 256

= 1

Step3:

LCM(1, 648) = 648

GCD(1, 648) = ( 1 x 648 ) / 648

= 1 / 648

= 1

So, Greatest Common Divisor of 605, 873, 256, 648 is 1
