Given numbers are 489, 249, 418, 580

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

Apply this formula for all numbers.

Step1:

LCM(489, 249) = 40587

GCD(489, 249) = ( 489 x 249 ) / 40587

= 489 / 249

= 489

Step2:

LCM(3, 418) = 1254

GCD(3, 418) = ( 3 x 418 ) / 1254

= 3 / 418

= 3

Step3:

LCM(1, 580) = 580

GCD(1, 580) = ( 1 x 580 ) / 580

= 1 / 580

= 1

So, Greatest Common Divisor of 489, 249, 418, 580 is 1
