Given Input Data is 639, 675, 378, 563

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 378 is 2 x 3 x 3 x 3 x 7

Prime Factorization of 563 is 563

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 378

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

LCM(9, 378) = 378

GCD(9, 378) = ( 9 x 378 ) / 378

GCD(9, 378) = 3402 / 378

GCD(9, 378) = 9

Step3:

Here we consider the GCD from the above i.e. 9 as first number and the next as 563

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

LCM(9, 563) = 5067

GCD(9, 563) = ( 9 x 563 ) / 5067

GCD(9, 563) = 5067 / 5067

GCD(9, 563) = 1

GCD of 639, 675, 378, 563 is 1
