Given Input Data is 243, 231, 974, 570

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

Prime Factorization of 243 is 3 x 3 x 3 x 3 x 3

Prime Factorization of 231 is 3 x 7 x 11

Prime Factorization of 974 is 2 x 487

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

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(243, 231) = 18711

GCD(243, 231) = ( 243 x 231 ) / 18711

GCD(243, 231) = 56133 / 18711

GCD(243, 231) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 974

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

LCM(3, 974) = 2922

GCD(3, 974) = ( 3 x 974 ) / 2922

GCD(3, 974) = 2922 / 2922

GCD(3, 974) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 570

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

LCM(1, 570) = 570

GCD(1, 570) = ( 1 x 570 ) / 570

GCD(1, 570) = 570 / 570

GCD(1, 570) = 1

GCD of 243, 231, 974, 570 is 1
