Given Input Data is 639, 585, 199, 663

Make a list of Prime Factors of all the given numbers initially

Prime Factorization of 639 is 3 x 3 x 71

Prime Factorization of 585 is 3 x 3 x 5 x 13

Prime Factorization of 199 is 199

Prime Factorization of 663 is 3 x 13 x 17

The above numbers do not have any common prime factor. So GCD is 1

Step1:

Let's calculate the GCD of first two numbers

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

LCM(639, 585) = 41535

GCD(639, 585) = ( 639 x 585 ) / 41535

GCD(639, 585) = 373815 / 41535

GCD(639, 585) = 9

Step2:

Here we consider the GCD from the above i.e. 9 as first number and the next as 199

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

LCM(9, 199) = 1791

GCD(9, 199) = ( 9 x 199 ) / 1791

GCD(9, 199) = 1791 / 1791

GCD(9, 199) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 663

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

LCM(1, 663) = 663

GCD(1, 663) = ( 1 x 663 ) / 663

GCD(1, 663) = 663 / 663

GCD(1, 663) = 1

GCD of 639, 585, 199, 663 is 1
