Given Input Data is 423, 948, 570, 647

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

Prime Factorization of 423 is 3 x 3 x 47

Prime Factorization of 948 is 2 x 2 x 3 x 79

Prime Factorization of 570 is 2 x 3 x 5 x 19

Prime Factorization of 647 is 647

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(423, 948) = 133668

GCD(423, 948) = ( 423 x 948 ) / 133668

GCD(423, 948) = 401004 / 133668

GCD(423, 948) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 570

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

LCM(3, 570) = 570

GCD(3, 570) = ( 3 x 570 ) / 570

GCD(3, 570) = 1710 / 570

GCD(3, 570) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 647

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

LCM(3, 647) = 1941

GCD(3, 647) = ( 3 x 647 ) / 1941

GCD(3, 647) = 1941 / 1941

GCD(3, 647) = 1

GCD of 423, 948, 570, 647 is 1
