The list of prime factors of all numbers are

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

Prime factors of 686 are 2 x 7 x 7 x 7

Prime factors of 863 are 863

Prime factors of 408 are 2 x 2 x 2 x 3 x 17

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

Given numbers are 928, 686, 863, 408

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

Apply this formula for all numbers.

Step1:

LCM(928, 686) = 318304

GCD(928, 686) = ( 928 x 686 ) / 318304

= 928 / 686

= 928

Step2:

LCM(2, 863) = 1726

GCD(2, 863) = ( 2 x 863 ) / 1726

= 2 / 863

= 2

Step3:

LCM(1, 408) = 408

GCD(1, 408) = ( 1 x 408 ) / 408

= 1 / 408

= 1

So, Greatest Common Divisor of 928, 686, 863, 408 is 1
