Given Input Data is 664, 628, 363, 611

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

Prime Factorization of 664 is 2 x 2 x 2 x 83

Prime Factorization of 628 is 2 x 2 x 157

Prime Factorization of 363 is 3 x 11 x 11

Prime Factorization of 611 is 13 x 47

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(664, 628) = 104248

GCD(664, 628) = ( 664 x 628 ) / 104248

GCD(664, 628) = 416992 / 104248

GCD(664, 628) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 363

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

LCM(4, 363) = 1452

GCD(4, 363) = ( 4 x 363 ) / 1452

GCD(4, 363) = 1452 / 1452

GCD(4, 363) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 611

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

LCM(1, 611) = 611

GCD(1, 611) = ( 1 x 611 ) / 611

GCD(1, 611) = 611 / 611

GCD(1, 611) = 1

GCD of 664, 628, 363, 611 is 1
