The list of prime factors of all numbers are

Prime factors of 685 are 5 x 137

Prime factors of 681 are 3 x 227

Prime factors of 348 are 2 x 2 x 3 x 29

Prime factors of 813 are 3 x 271

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

Given numbers are 685, 681, 348, 813

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

Apply this formula for all numbers.

Step1:

LCM(685, 681) = 466485

GCD(685, 681) = ( 685 x 681 ) / 466485

= 685 / 681

= 685

Step2:

LCM(1, 348) = 348

GCD(1, 348) = ( 1 x 348 ) / 348

= 1 / 348

= 1

Step3:

LCM(1, 813) = 813

GCD(1, 813) = ( 1 x 813 ) / 813

= 1 / 813

= 1

So, Greatest Common Divisor of 685, 681, 348, 813 is 1
