Given numbers are 686, 495, 943, 405

The list of prime factors of all numbers are

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

Prime factors of 495 are 3 x 3 x 5 x 11

Prime factors of 943 are 23 x 41

Prime factors of 405 are 3 x 3 x 3 x 3 x 5

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

Given numbers are 686, 495, 943, 405

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

Apply this formula for all numbers.

Step1:

LCM(686, 495) = 339570

GCD(686, 495) = ( 686 x 495 ) / 339570

= 686 / 495

= 686

Step2:

LCM(1, 943) = 943

GCD(1, 943) = ( 1 x 943 ) / 943

= 1 / 943

= 1

Step3:

LCM(1, 405) = 405

GCD(1, 405) = ( 1 x 405 ) / 405

= 1 / 405

= 1

So, Greatest Common Divisor of 686, 495, 943, 405 is 1
