Given numbers are 243, 780, 657, 449

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

Apply this formula for all numbers.

Step1:

LCM(243, 780) = 63180

GCD(243, 780) = ( 243 x 780 ) / 63180

= 243 / 780

= 243

Step2:

LCM(3, 657) = 657

GCD(3, 657) = ( 3 x 657 ) / 657

= 3 / 657

= 3

Step3:

LCM(3, 449) = 1347

GCD(3, 449) = ( 3 x 449 ) / 1347

= 3 / 449

= 3

So, Greatest Common Divisor of 243, 780, 657, 449 is 1
