Given numbers are 663, 399, 481, 824

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

Apply this formula for all numbers.

Step1:

LCM(663, 399) = 88179

GCD(663, 399) = ( 663 x 399 ) / 88179

= 663 / 399

= 663

Step2:

LCM(3, 481) = 1443

GCD(3, 481) = ( 3 x 481 ) / 1443

= 3 / 481

= 3

Step3:

LCM(1, 824) = 824

GCD(1, 824) = ( 1 x 824 ) / 824

= 1 / 824

= 1

So, Greatest Common Divisor of 663, 399, 481, 824 is 1
