Given Input Data is 175, 252, 647, 422

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

Prime Factorization of 175 is 5 x 5 x 7

Prime Factorization of 252 is 2 x 2 x 3 x 3 x 7

Prime Factorization of 647 is 647

Prime Factorization of 422 is 2 x 211

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(175, 252) = 6300

GCD(175, 252) = ( 175 x 252 ) / 6300

GCD(175, 252) = 44100 / 6300

GCD(175, 252) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 647

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

LCM(7, 647) = 4529

GCD(7, 647) = ( 7 x 647 ) / 4529

GCD(7, 647) = 4529 / 4529

GCD(7, 647) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 422

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

LCM(1, 422) = 422

GCD(1, 422) = ( 1 x 422 ) / 422

GCD(1, 422) = 422 / 422

GCD(1, 422) = 1

GCD of 175, 252, 647, 422 is 1
