Given numbers are 686, 679, 756, 794

The list of prime factors of all numbers are

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

Prime factors of 679 are 7 x 97

Prime factors of 756 are 2 x 2 x 3 x 3 x 3 x 7

Prime factors of 794 are 2 x 397

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

Given numbers are 686, 679, 756, 794

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

Apply this formula for all numbers.

Step1:

LCM(686, 679) = 66542

GCD(686, 679) = ( 686 x 679 ) / 66542

= 686 / 679

= 686

Step2:

LCM(7, 756) = 756

GCD(7, 756) = ( 7 x 756 ) / 756

= 7 / 756

= 7

Step3:

LCM(7, 794) = 5558

GCD(7, 794) = ( 7 x 794 ) / 5558

= 7 / 794

= 7

So, Greatest Common Divisor of 686, 679, 756, 794 is 1
