Given numbers are 530, 780, 518

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

Apply this formula for all numbers.

Step1:

LCM(530, 780) = 41340

GCD(530, 780) = ( 530 x 780 ) / 41340

= 530 / 780

= 530

Step2:

LCM(10, 518) = 2590

GCD(10, 518) = ( 10 x 518 ) / 2590

= 10 / 518

= 10

So, Greatest Common Divisor of 530, 780, 518 is 2
