Therefore, GCD of numbers 30, 531, 437, 956 is 1

Given Input Data is 30, 531, 437, 956

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

Prime Factorization of 30 is 2 x 3 x 5

Prime Factorization of 531 is 3 x 3 x 59

Prime Factorization of 437 is 19 x 23

Prime Factorization of 956 is 2 x 2 x 239

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(30, 531) = 5310

GCD(30, 531) = ( 30 x 531 ) / 5310

GCD(30, 531) = 15930 / 5310

GCD(30, 531) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 437

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

LCM(3, 437) = 1311

GCD(3, 437) = ( 3 x 437 ) / 1311

GCD(3, 437) = 1311 / 1311

GCD(3, 437) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 956

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

LCM(1, 956) = 956

GCD(1, 956) = ( 1 x 956 ) / 956

GCD(1, 956) = 956 / 956

GCD(1, 956) = 1

GCD of 30, 531, 437, 956 is 1
