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

Apply this formula for all numbers.

Step1:

LCM(663, 747) = 165087

GCD(663, 747) = ( 663 x 747 ) / 165087

= 663 / 747

= 663

Step2:

LCM(3, 426) = 426

GCD(3, 426) = ( 3 x 426 ) / 426

= 3 / 426

= 3

Step3:

LCM(3, 303) = 303

GCD(3, 303) = ( 3 x 303 ) / 303

= 3 / 303

= 3

So, Greatest Common Divisor of 663, 747, 426, 303 is 3
