Given Input Data is 648, 801, 249, 139

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 801 is 3 x 3 x 89

Prime Factorization of 249 is 3 x 83

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(648, 801) = 57672

GCD(648, 801) = ( 648 x 801 ) / 57672

GCD(648, 801) = 519048 / 57672

GCD(648, 801) = 9

Step2:

Here we consider the GCD from the above i.e. 9 as first number and the next as 249

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

LCM(9, 249) = 747

GCD(9, 249) = ( 9 x 249 ) / 747

GCD(9, 249) = 2241 / 747

GCD(9, 249) = 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 648, 801, 249, 139 is 1
