Given numbers are 771, 638, 555, 928

The list of prime factors of all numbers are

Prime factors of 771 are 3 x 257

Prime factors of 638 are 2 x 11 x 29

Prime factors of 555 are 3 x 5 x 37

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

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

Given numbers are 771, 638, 555, 928

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

Apply this formula for all numbers.

Step1:

LCM(771, 638) = 491898

GCD(771, 638) = ( 771 x 638 ) / 491898

= 771 / 638

= 771

Step2:

LCM(1, 555) = 555

GCD(1, 555) = ( 1 x 555 ) / 555

= 1 / 555

= 1

Step3:

LCM(1, 928) = 928

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

= 1 / 928

= 1

So, Greatest Common Divisor of 771, 638, 555, 928 is 1
