Given Input Data is 648, 267, 842, 428

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

Prime Factorization of 648 is 2 x 2 x 2 x 3 x 3 x 3 x 3

Prime Factorization of 267 is 3 x 89

Prime Factorization of 842 is 2 x 421

Prime Factorization of 428 is 2 x 2 x 107

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(648, 267) = 57672

GCD(648, 267) = ( 648 x 267 ) / 57672

GCD(648, 267) = 173016 / 57672

GCD(648, 267) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 842

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

LCM(3, 842) = 2526

GCD(3, 842) = ( 3 x 842 ) / 2526

GCD(3, 842) = 2526 / 2526

GCD(3, 842) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 428

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

LCM(1, 428) = 428

GCD(1, 428) = ( 1 x 428 ) / 428

GCD(1, 428) = 428 / 428

GCD(1, 428) = 1

GCD of 648, 267, 842, 428 is 1
