Given numbers are 530, 518, 405, 939

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

Apply this formula for all numbers.

Step1:

LCM(530, 518) = 137270

GCD(530, 518) = ( 530 x 518 ) / 137270

= 530 / 518

= 530

Step2:

LCM(2, 405) = 810

GCD(2, 405) = ( 2 x 405 ) / 810

= 2 / 405

= 2

Step3:

LCM(1, 939) = 939

GCD(1, 939) = ( 1 x 939 ) / 939

= 1 / 939

= 1

So, Greatest Common Divisor of 530, 518, 405, 939 is 1
