Given Input Data is 648, 570, 104, 873

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 570 is 2 x 3 x 5 x 19

Prime Factorization of 104 is 2 x 2 x 2 x 13

Prime Factorization of 873 is 3 x 3 x 97

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, 570) = 61560

GCD(648, 570) = ( 648 x 570 ) / 61560

GCD(648, 570) = 369360 / 61560

GCD(648, 570) = 6

Step2:

Here we consider the GCD from the above i.e. 6 as first number and the next as 104

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

LCM(6, 104) = 312

GCD(6, 104) = ( 6 x 104 ) / 312

GCD(6, 104) = 624 / 312

GCD(6, 104) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 873

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

LCM(2, 873) = 1746

GCD(2, 873) = ( 2 x 873 ) / 1746

GCD(2, 873) = 1746 / 1746

GCD(2, 873) = 1

GCD of 648, 570, 104, 873 is 1
