The list of prime factors of all numbers are

Prime factors of 687 are 3 x 229

Prime factors of 844 are 2 x 2 x 211

Prime factors of 819 are 3 x 3 x 7 x 13

Prime factors of 768 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 3

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

Given numbers are 687, 844, 819, 768

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

Apply this formula for all numbers.

Step1:

LCM(687, 844) = 579828

GCD(687, 844) = ( 687 x 844 ) / 579828

= 687 / 844

= 687

Step2:

LCM(1, 819) = 819

GCD(1, 819) = ( 1 x 819 ) / 819

= 1 / 819

= 1

Step3:

LCM(1, 768) = 768

GCD(1, 768) = ( 1 x 768 ) / 768

= 1 / 768

= 1

So, Greatest Common Divisor of 687, 844, 819, 768 is 1
