Given numbers are 518, 911, 685, 420

The list of prime factors of all numbers are

Prime factors of 518 are 2 x 7 x 37

Prime factors of 911 are 911

Prime factors of 685 are 5 x 137

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

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

Given numbers are 518, 911, 685, 420

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

Apply this formula for all numbers.

Step1:

LCM(518, 911) = 471898

GCD(518, 911) = ( 518 x 911 ) / 471898

= 518 / 911

= 518

Step2:

LCM(1, 685) = 685

GCD(1, 685) = ( 1 x 685 ) / 685

= 1 / 685

= 1

Step3:

LCM(1, 420) = 420

GCD(1, 420) = ( 1 x 420 ) / 420

= 1 / 420

= 1

So, Greatest Common Divisor of 518, 911, 685, 420 is 1
