Given Input Data is 396, 869, 81, 481

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

Prime Factorization of 396 is 2 x 2 x 3 x 3 x 11

Prime Factorization of 869 is 11 x 79

Prime Factorization of 81 is 3 x 3 x 3 x 3

Prime Factorization of 481 is 13 x 37

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(396, 869) = 31284

GCD(396, 869) = ( 396 x 869 ) / 31284

GCD(396, 869) = 344124 / 31284

GCD(396, 869) = 11

Step2:

Here we consider the GCD from the above i.e. 11 as first number and the next as 81

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

LCM(11, 81) = 891

GCD(11, 81) = ( 11 x 81 ) / 891

GCD(11, 81) = 891 / 891

GCD(11, 81) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 481

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

LCM(1, 481) = 481

GCD(1, 481) = ( 1 x 481 ) / 481

GCD(1, 481) = 481 / 481

GCD(1, 481) = 1

GCD of 396, 869, 81, 481 is 1
