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

Apply this formula for all numbers.

Step1:

LCM(423, 108) = 5076

GCD(423, 108) = ( 423 x 108 ) / 5076

= 423 / 108

= 423

Step2:

LCM(9, 489) = 1467

GCD(9, 489) = ( 9 x 489 ) / 1467

= 9 / 489

= 9

Step3:

LCM(3, 513) = 513

GCD(3, 513) = ( 3 x 513 ) / 513

= 3 / 513

= 3

So, Greatest Common Divisor of 423, 108, 489, 513 is 3
