Given Input Data is 660, 908, 481, 397

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

Prime Factorization of 660 is 2 x 2 x 3 x 5 x 11

Prime Factorization of 908 is 2 x 2 x 227

Prime Factorization of 481 is 13 x 37

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(660, 908) = 149820

GCD(660, 908) = ( 660 x 908 ) / 149820

GCD(660, 908) = 599280 / 149820

GCD(660, 908) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 481

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

LCM(4, 481) = 1924

GCD(4, 481) = ( 4 x 481 ) / 1924

GCD(4, 481) = 1924 / 1924

GCD(4, 481) = 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 660, 908, 481, 397 is 1
