Given numbers are 686, 865, 910, 634

The list of prime factors of all numbers are

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

Prime factors of 865 are 5 x 173

Prime factors of 910 are 2 x 5 x 7 x 13

Prime factors of 634 are 2 x 317

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

Given numbers are 686, 865, 910, 634

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

Apply this formula for all numbers.

Step1:

LCM(686, 865) = 593390

GCD(686, 865) = ( 686 x 865 ) / 593390

= 686 / 865

= 686

Step2:

LCM(1, 910) = 910

GCD(1, 910) = ( 1 x 910 ) / 910

= 1 / 910

= 1

Step3:

LCM(1, 634) = 634

GCD(1, 634) = ( 1 x 634 ) / 634

= 1 / 634

= 1

So, Greatest Common Divisor of 686, 865, 910, 634 is 1
