The list of prime factors of all numbers are

Prime factors of 555 are 3 x 5 x 37

Prime factors of 657 are 3 x 3 x 73

Prime factors of 745 are 5 x 149

Prime factors of 778 are 2 x 389

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

Given numbers are 555, 657, 745, 778

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

Apply this formula for all numbers.

Step1:

LCM(555, 657) = 121545

GCD(555, 657) = ( 555 x 657 ) / 121545

= 555 / 657

= 555

Step2:

LCM(3, 745) = 2235

GCD(3, 745) = ( 3 x 745 ) / 2235

= 3 / 745

= 3

Step3:

LCM(1, 778) = 778

GCD(1, 778) = ( 1 x 778 ) / 778

= 1 / 778

= 1

So, Greatest Common Divisor of 555, 657, 745, 778 is 1
