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

Apply this formula for all numbers.

Step1:

LCM(663, 945) = 208845

GCD(663, 945) = ( 663 x 945 ) / 208845

= 663 / 945

= 663

Step2:

LCM(3, 570) = 570

GCD(3, 570) = ( 3 x 570 ) / 570

= 3 / 570

= 3

Step3:

LCM(3, 294) = 294

GCD(3, 294) = ( 3 x 294 ) / 294

= 3 / 294

= 3

So, Greatest Common Divisor of 663, 945, 570, 294 is 3
