Given numbers are 530, 439, 686, 515

The list of prime factors of all numbers are

Prime factors of 530 are 2 x 5 x 53

Prime factors of 439 are 439

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

Prime factors of 515 are 5 x 103

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

Given numbers are 530, 439, 686, 515

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

Apply this formula for all numbers.

Step1:

LCM(530, 439) = 232670

GCD(530, 439) = ( 530 x 439 ) / 232670

= 530 / 439

= 530

Step2:

LCM(1, 686) = 686

GCD(1, 686) = ( 1 x 686 ) / 686

= 1 / 686

= 1

Step3:

LCM(1, 515) = 515

GCD(1, 515) = ( 1 x 515 ) / 515

= 1 / 515

= 1

So, Greatest Common Divisor of 530, 439, 686, 515 is 1
