The list of prime factors of all numbers are

Prime factors of 555 are 3 x 5 x 37

Prime factors of 925 are 5 x 5 x 37

Prime factors of 642 are 2 x 3 x 107

Prime factors of 728 are 2 x 2 x 2 x 7 x 13

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

Given numbers are 555, 925, 642, 728

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

Apply this formula for all numbers.

Step1:

LCM(555, 925) = 2775

GCD(555, 925) = ( 555 x 925 ) / 2775

= 555 / 925

= 555

Step2:

LCM(185, 642) = 118770

GCD(185, 642) = ( 185 x 642 ) / 118770

= 185 / 642

= 185

Step3:

LCM(1, 728) = 728

GCD(1, 728) = ( 1 x 728 ) / 728

= 1 / 728

= 1

So, Greatest Common Divisor of 555, 925, 642, 728 is 1
