Given numbers are 686, 884, 315, 858

The list of prime factors of all numbers are

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

Prime factors of 884 are 2 x 2 x 13 x 17

Prime factors of 315 are 3 x 3 x 5 x 7

Prime factors of 858 are 2 x 3 x 11 x 13

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

Given numbers are 686, 884, 315, 858

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

Apply this formula for all numbers.

Step1:

LCM(686, 884) = 303212

GCD(686, 884) = ( 686 x 884 ) / 303212

= 686 / 884

= 686

Step2:

LCM(2, 315) = 630

GCD(2, 315) = ( 2 x 315 ) / 630

= 2 / 315

= 2

Step3:

LCM(1, 858) = 858

GCD(1, 858) = ( 1 x 858 ) / 858

= 1 / 858

= 1

So, Greatest Common Divisor of 686, 884, 315, 858 is 1
