Given numbers are 393, 449, 203, 618

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

Apply this formula for all numbers.

Step1:

LCM(393, 449) = 176457

GCD(393, 449) = ( 393 x 449 ) / 176457

= 393 / 449

= 393

Step2:

LCM(1, 203) = 203

GCD(1, 203) = ( 1 x 203 ) / 203

= 1 / 203

= 1

Step3:

LCM(1, 618) = 618

GCD(1, 618) = ( 1 x 618 ) / 618

= 1 / 618

= 1

So, Greatest Common Divisor of 393, 449, 203, 618 is 1
