Given Input Data is 578, 119, 81, 397

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

Prime Factorization of 578 is 2 x 17 x 17

Prime Factorization of 119 is 7 x 17

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

Prime Factorization of 397 is 397

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(578, 119) = 4046

GCD(578, 119) = ( 578 x 119 ) / 4046

GCD(578, 119) = 68782 / 4046

GCD(578, 119) = 17

Step2:

Here we consider the GCD from the above i.e. 17 as first number and the next as 81

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

LCM(17, 81) = 1377

GCD(17, 81) = ( 17 x 81 ) / 1377

GCD(17, 81) = 1377 / 1377

GCD(17, 81) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 397

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

LCM(1, 397) = 397

GCD(1, 397) = ( 1 x 397 ) / 397

GCD(1, 397) = 397 / 397

GCD(1, 397) = 1

GCD of 578, 119, 81, 397 is 1
