Given Input Data is 648, 248, 794, 133

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 248 is 2 x 2 x 2 x 31

Prime Factorization of 794 is 2 x 397

Prime Factorization of 133 is 7 x 19

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, 248) = 20088

GCD(648, 248) = ( 648 x 248 ) / 20088

GCD(648, 248) = 160704 / 20088

GCD(648, 248) = 8

Step2:

Here we consider the GCD from the above i.e. 8 as first number and the next as 794

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

LCM(8, 794) = 3176

GCD(8, 794) = ( 8 x 794 ) / 3176

GCD(8, 794) = 6352 / 3176

GCD(8, 794) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 133

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

LCM(2, 133) = 266

GCD(2, 133) = ( 2 x 133 ) / 266

GCD(2, 133) = 266 / 266

GCD(2, 133) = 1

GCD of 648, 248, 794, 133 is 1
