The list of prime factors of all numbers are

Prime factors of 455 are 5 x 7 x 13

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

Prime factors of 928 are 2 x 2 x 2 x 2 x 2 x 29

Prime factors of 756 are 2 x 2 x 3 x 3 x 3 x 7

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

Given numbers are 455, 342, 928, 756

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

Apply this formula for all numbers.

Step1:

LCM(455, 342) = 155610

GCD(455, 342) = ( 455 x 342 ) / 155610

= 455 / 342

= 455

Step2:

LCM(1, 928) = 928

GCD(1, 928) = ( 1 x 928 ) / 928

= 1 / 928

= 1

Step3:

LCM(1, 756) = 756

GCD(1, 756) = ( 1 x 756 ) / 756

= 1 / 756

= 1

So, Greatest Common Divisor of 455, 342, 928, 756 is 1
