Given numbers are 489, 403, 647, 498

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

Apply this formula for all numbers.

Step1:

LCM(489, 403) = 197067

GCD(489, 403) = ( 489 x 403 ) / 197067

= 489 / 403

= 489

Step2:

LCM(1, 647) = 647

GCD(1, 647) = ( 1 x 647 ) / 647

= 1 / 647

= 1

Step3:

LCM(1, 498) = 498

GCD(1, 498) = ( 1 x 498 ) / 498

= 1 / 498

= 1

So, Greatest Common Divisor of 489, 403, 647, 498 is 1
