Given numbers are 663, 921, 457, 418

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

Apply this formula for all numbers.

Step1:

LCM(663, 921) = 203541

GCD(663, 921) = ( 663 x 921 ) / 203541

= 663 / 921

= 663

Step2:

LCM(3, 457) = 1371

GCD(3, 457) = ( 3 x 457 ) / 1371

= 3 / 457

= 3

Step3:

LCM(1, 418) = 418

GCD(1, 418) = ( 1 x 418 ) / 418

= 1 / 418

= 1

So, Greatest Common Divisor of 663, 921, 457, 418 is 1
