Given numbers are 225, 129, 489, 210

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

Apply this formula for all numbers.

Step1:

LCM(225, 129) = 9675

GCD(225, 129) = ( 225 x 129 ) / 9675

= 225 / 129

= 225

Step2:

LCM(3, 489) = 489

GCD(3, 489) = ( 3 x 489 ) / 489

= 3 / 489

= 3

Step3:

LCM(3, 210) = 210

GCD(3, 210) = ( 3 x 210 ) / 210

= 3 / 210

= 3

So, Greatest Common Divisor of 225, 129, 489, 210 is 3
