Given numbers are 317, 688, 256, 342

The list of prime factors of all numbers are

Prime factors of 317 are 317

Prime factors of 688 are 2 x 2 x 2 x 2 x 43

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

Prime factors of 342 are 2 x 3 x 3 x 19

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

Given numbers are 317, 688, 256, 342

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

Apply this formula for all numbers.

Step1:

LCM(317, 688) = 218096

GCD(317, 688) = ( 317 x 688 ) / 218096

= 317 / 688

= 317

Step2:

LCM(1, 256) = 256

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

= 1 / 256

= 1

Step3:

LCM(1, 342) = 342

GCD(1, 342) = ( 1 x 342 ) / 342

= 1 / 342

= 1

So, Greatest Common Divisor of 317, 688, 256, 342 is 1
