Given numbers are 243, 449, 609, 518

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

Apply this formula for all numbers.

Step1:

LCM(243, 449) = 109107

GCD(243, 449) = ( 243 x 449 ) / 109107

= 243 / 449

= 243

Step2:

LCM(1, 609) = 609

GCD(1, 609) = ( 1 x 609 ) / 609

= 1 / 609

= 1

Step3:

LCM(1, 518) = 518

GCD(1, 518) = ( 1 x 518 ) / 518

= 1 / 518

= 1

So, Greatest Common Divisor of 243, 449, 609, 518 is 1
