Given numbers are 663, 393, 210, 209

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

Apply this formula for all numbers.

Step1:

LCM(663, 393) = 86853

GCD(663, 393) = ( 663 x 393 ) / 86853

= 663 / 393

= 663

Step2:

LCM(3, 210) = 210

GCD(3, 210) = ( 3 x 210 ) / 210

= 3 / 210

= 3

Step3:

LCM(3, 209) = 627

GCD(3, 209) = ( 3 x 209 ) / 627

= 3 / 209

= 3

So, Greatest Common Divisor of 663, 393, 210, 209 is 1
