The list of prime factors of all numbers are

Prime factors of 403 are 13 x 31

Prime factors of 555 are 3 x 5 x 37

Prime factors of 322 are 2 x 7 x 23

Prime factors of 689 are 13 x 53

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

Given numbers are 403, 555, 322, 689

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

Apply this formula for all numbers.

Step1:

LCM(403, 555) = 223665

GCD(403, 555) = ( 403 x 555 ) / 223665

= 403 / 555

= 403

Step2:

LCM(1, 322) = 322

GCD(1, 322) = ( 1 x 322 ) / 322

= 1 / 322

= 1

Step3:

LCM(1, 689) = 689

GCD(1, 689) = ( 1 x 689 ) / 689

= 1 / 689

= 1

So, Greatest Common Divisor of 403, 555, 322, 689 is 1
