Given numbers are 681, 720, 663, 624

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

Apply this formula for all numbers.

Step1:

LCM(681, 720) = 163440

GCD(681, 720) = ( 681 x 720 ) / 163440

= 681 / 720

= 681

Step2:

LCM(3, 663) = 663

GCD(3, 663) = ( 3 x 663 ) / 663

= 3 / 663

= 3

Step3:

LCM(3, 624) = 624

GCD(3, 624) = ( 3 x 624 ) / 624

= 3 / 624

= 3

So, Greatest Common Divisor of 681, 720, 663, 624 is 3
