The list of prime factors of all numbers are

Prime factors of 687 are 3 x 229

Prime factors of 815 are 5 x 163

Prime factors of 854 are 2 x 7 x 61

Prime factors of 371 are 7 x 53

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

Given numbers are 687, 815, 854, 371

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

Apply this formula for all numbers.

Step1:

LCM(687, 815) = 559905

GCD(687, 815) = ( 687 x 815 ) / 559905

= 687 / 815

= 687

Step2:

LCM(1, 854) = 854

GCD(1, 854) = ( 1 x 854 ) / 854

= 1 / 854

= 1

Step3:

LCM(1, 371) = 371

GCD(1, 371) = ( 1 x 371 ) / 371

= 1 / 371

= 1

So, Greatest Common Divisor of 687, 815, 854, 371 is 1
