Given numbers are 663, 219, 654, 403

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

Apply this formula for all numbers.

Step1:

LCM(663, 219) = 48399

GCD(663, 219) = ( 663 x 219 ) / 48399

= 663 / 219

= 663

Step2:

LCM(3, 654) = 654

GCD(3, 654) = ( 3 x 654 ) / 654

= 3 / 654

= 3

Step3:

LCM(3, 403) = 1209

GCD(3, 403) = ( 3 x 403 ) / 1209

= 3 / 403

= 3

So, Greatest Common Divisor of 663, 219, 654, 403 is 1
