Given numbers are 663, 645, 36, 630

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

Apply this formula for all numbers.

Step1:

LCM(663, 645) = 142545

GCD(663, 645) = ( 663 x 645 ) / 142545

= 663 / 645

= 663

Step2:

LCM(3, 36) = 36

GCD(3, 36) = ( 3 x 36 ) / 36

= 3 / 36

= 3

Step3:

LCM(3, 630) = 630

GCD(3, 630) = ( 3 x 630 ) / 630

= 3 / 630

= 3

So, Greatest Common Divisor of 663, 645, 36, 630 is 3
