Given numbers are 687, 646, 683, 936

The list of prime factors of all numbers are

Prime factors of 687 are 3 x 229

Prime factors of 646 are 2 x 17 x 19

Prime factors of 683 are 683

Prime factors of 936 are 2 x 2 x 2 x 3 x 3 x 13

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

Given numbers are 687, 646, 683, 936

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

Apply this formula for all numbers.

Step1:

LCM(687, 646) = 443802

GCD(687, 646) = ( 687 x 646 ) / 443802

= 687 / 646

= 687

Step2:

LCM(1, 683) = 683

GCD(1, 683) = ( 1 x 683 ) / 683

= 1 / 683

= 1

Step3:

LCM(1, 936) = 936

GCD(1, 936) = ( 1 x 936 ) / 936

= 1 / 936

= 1

So, Greatest Common Divisor of 687, 646, 683, 936 is 1
