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

Apply this formula for all numbers.

Step1:

LCM(243, 909) = 24543

GCD(243, 909) = ( 243 x 909 ) / 24543

= 243 / 909

= 243

Step2:

LCM(9, 393) = 1179

GCD(9, 393) = ( 9 x 393 ) / 1179

= 9 / 393

= 9

Step3:

LCM(3, 450) = 450

GCD(3, 450) = ( 3 x 450 ) / 450

= 3 / 450

= 3

So, Greatest Common Divisor of 243, 909, 393, 450 is 3
