Given numbers are 351, 912, 717, 686

The list of prime factors of all numbers are

Prime factors of 351 are 3 x 3 x 3 x 13

Prime factors of 912 are 2 x 2 x 2 x 2 x 3 x 19

Prime factors of 717 are 3 x 239

Prime factors of 686 are 2 x 7 x 7 x 7

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

Given numbers are 351, 912, 717, 686

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

Apply this formula for all numbers.

Step1:

LCM(351, 912) = 106704

GCD(351, 912) = ( 351 x 912 ) / 106704

= 351 / 912

= 351

Step2:

LCM(3, 717) = 717

GCD(3, 717) = ( 3 x 717 ) / 717

= 3 / 717

= 3

Step3:

LCM(3, 686) = 2058

GCD(3, 686) = ( 3 x 686 ) / 2058

= 3 / 686

= 3

So, Greatest Common Divisor of 351, 912, 717, 686 is 1
