Given Input Data is 132, 385, 644, 397

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

Prime Factorization of 132 is 2 x 2 x 3 x 11

Prime Factorization of 385 is 5 x 7 x 11

Prime Factorization of 644 is 2 x 2 x 7 x 23

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(132, 385) = 4620

GCD(132, 385) = ( 132 x 385 ) / 4620

GCD(132, 385) = 50820 / 4620

GCD(132, 385) = 11

Step2:

Here we consider the GCD from the above i.e. 11 as first number and the next as 644

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

LCM(11, 644) = 7084

GCD(11, 644) = ( 11 x 644 ) / 7084

GCD(11, 644) = 7084 / 7084

GCD(11, 644) = 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 132, 385, 644, 397 is 1
