Given Input Data is 405, 648, 352, 963

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

Prime Factorization of 405 is 3 x 3 x 3 x 3 x 5

Prime Factorization of 648 is 2 x 2 x 2 x 3 x 3 x 3 x 3

Prime Factorization of 352 is 2 x 2 x 2 x 2 x 2 x 11

Prime Factorization of 963 is 3 x 3 x 107

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(405, 648) = 3240

GCD(405, 648) = ( 405 x 648 ) / 3240

GCD(405, 648) = 262440 / 3240

GCD(405, 648) = 81

Step2:

Here we consider the GCD from the above i.e. 81 as first number and the next as 352

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

LCM(81, 352) = 28512

GCD(81, 352) = ( 81 x 352 ) / 28512

GCD(81, 352) = 28512 / 28512

GCD(81, 352) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 963

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

LCM(1, 963) = 963

GCD(1, 963) = ( 1 x 963 ) / 963

GCD(1, 963) = 963 / 963

GCD(1, 963) = 1

GCD of 405, 648, 352, 963 is 1
