Given Input Data is 126, 805, 865, 845

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

Prime Factorization of 126 is 2 x 3 x 3 x 7

Prime Factorization of 805 is 5 x 7 x 23

Prime Factorization of 865 is 5 x 173

Prime Factorization of 845 is 5 x 13 x 13

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(126, 805) = 14490

GCD(126, 805) = ( 126 x 805 ) / 14490

GCD(126, 805) = 101430 / 14490

GCD(126, 805) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 865

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

LCM(7, 865) = 6055

GCD(7, 865) = ( 7 x 865 ) / 6055

GCD(7, 865) = 6055 / 6055

GCD(7, 865) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 845

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

LCM(1, 845) = 845

GCD(1, 845) = ( 1 x 845 ) / 845

GCD(1, 845) = 845 / 845

GCD(1, 845) = 1

GCD of 126, 805, 865, 845 is 1
