Given numbers are 686, 121, 345, 586

The list of prime factors of all numbers are

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

Prime factors of 121 are 11 x 11

Prime factors of 345 are 3 x 5 x 23

Prime factors of 586 are 2 x 293

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

Given numbers are 686, 121, 345, 586

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

Apply this formula for all numbers.

Step1:

LCM(686, 121) = 83006

GCD(686, 121) = ( 686 x 121 ) / 83006

= 686 / 121

= 686

Step2:

LCM(1, 345) = 345

GCD(1, 345) = ( 1 x 345 ) / 345

= 1 / 345

= 1

Step3:

LCM(1, 586) = 586

GCD(1, 586) = ( 1 x 586 ) / 586

= 1 / 586

= 1

So, Greatest Common Divisor of 686, 121, 345, 586 is 1
