Given Input Data is 843, 951, 12, 139

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

Prime Factorization of 843 is 3 x 281

Prime Factorization of 951 is 3 x 317

Prime Factorization of 12 is 2 x 2 x 3

Prime Factorization of 139 is 139

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(843, 951) = 267231

GCD(843, 951) = ( 843 x 951 ) / 267231

GCD(843, 951) = 801693 / 267231

GCD(843, 951) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 12

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

LCM(3, 12) = 12

GCD(3, 12) = ( 3 x 12 ) / 12

GCD(3, 12) = 36 / 12

GCD(3, 12) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 139

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

LCM(3, 139) = 417

GCD(3, 139) = ( 3 x 139 ) / 417

GCD(3, 139) = 417 / 417

GCD(3, 139) = 1

GCD of 843, 951, 12, 139 is 1
