The list of prime factors of all numbers are

Prime factors of 687 are 3 x 229

Prime factors of 621 are 3 x 3 x 3 x 23

Prime factors of 695 are 5 x 139

Prime factors of 287 are 7 x 41

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

Given numbers are 687, 621, 695, 287

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

Apply this formula for all numbers.

Step1:

LCM(687, 621) = 142209

GCD(687, 621) = ( 687 x 621 ) / 142209

= 687 / 621

= 687

Step2:

LCM(3, 695) = 2085

GCD(3, 695) = ( 3 x 695 ) / 2085

= 3 / 695

= 3

Step3:

LCM(1, 287) = 287

GCD(1, 287) = ( 1 x 287 ) / 287

= 1 / 287

= 1

So, Greatest Common Divisor of 687, 621, 695, 287 is 1
