Given numbers are 686, 558, 834, 813

The list of prime factors of all numbers are

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

Prime factors of 558 are 2 x 3 x 3 x 31

Prime factors of 834 are 2 x 3 x 139

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 686, 558, 834, 813

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

Apply this formula for all numbers.

Step1:

LCM(686, 558) = 191394

GCD(686, 558) = ( 686 x 558 ) / 191394

= 686 / 558

= 686

Step2:

LCM(2, 834) = 834

GCD(2, 834) = ( 2 x 834 ) / 834

= 2 / 834

= 2

Step3:

LCM(2, 813) = 1626

GCD(2, 813) = ( 2 x 813 ) / 1626

= 2 / 813

= 2

So, Greatest Common Divisor of 686, 558, 834, 813 is 1
