Given Input Data is 639, 675, 286, 799

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 675 is 3 x 3 x 3 x 5 x 5

Prime Factorization of 286 is 2 x 11 x 13

Prime Factorization of 799 is 17 x 47

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, 675) = 47925

GCD(639, 675) = ( 639 x 675 ) / 47925

GCD(639, 675) = 431325 / 47925

GCD(639, 675) = 9

Step2:

Here we consider the GCD from the above i.e. 9 as first number and the next as 286

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

LCM(9, 286) = 2574

GCD(9, 286) = ( 9 x 286 ) / 2574

GCD(9, 286) = 2574 / 2574

GCD(9, 286) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 799

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

LCM(1, 799) = 799

GCD(1, 799) = ( 1 x 799 ) / 799

GCD(1, 799) = 799 / 799

GCD(1, 799) = 1

GCD of 639, 675, 286, 799 is 1
