Given numbers are 687, 323, 858, 506

The list of prime factors of all numbers are

Prime factors of 687 are 3 x 229

Prime factors of 323 are 17 x 19

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

Prime factors of 506 are 2 x 11 x 23

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

Given numbers are 687, 323, 858, 506

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

Apply this formula for all numbers.

Step1:

LCM(687, 323) = 221901

GCD(687, 323) = ( 687 x 323 ) / 221901

= 687 / 323

= 687

Step2:

LCM(1, 858) = 858

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

= 1 / 858

= 1

Step3:

LCM(1, 506) = 506

GCD(1, 506) = ( 1 x 506 ) / 506

= 1 / 506

= 1

So, Greatest Common Divisor of 687, 323, 858, 506 is 1
