Given numbers are 663, 187, 721, 984

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

Apply this formula for all numbers.

Step1:

LCM(663, 187) = 7293

GCD(663, 187) = ( 663 x 187 ) / 7293

= 663 / 187

= 663

Step2:

LCM(17, 721) = 12257

GCD(17, 721) = ( 17 x 721 ) / 12257

= 17 / 721

= 17

Step3:

LCM(1, 984) = 984

GCD(1, 984) = ( 1 x 984 ) / 984

= 1 / 984

= 1

So, Greatest Common Divisor of 663, 187, 721, 984 is 1
