Given Input Data is 731, 289, 531, 931

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

Prime Factorization of 731 is 17 x 43

Prime Factorization of 289 is 17 x 17

Prime Factorization of 531 is 3 x 3 x 59

Prime Factorization of 931 is 7 x 7 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(731, 289) = 12427

GCD(731, 289) = ( 731 x 289 ) / 12427

GCD(731, 289) = 211259 / 12427

GCD(731, 289) = 17

Step2:

Here we consider the GCD from the above i.e. 17 as first number and the next as 531

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

LCM(17, 531) = 9027

GCD(17, 531) = ( 17 x 531 ) / 9027

GCD(17, 531) = 9027 / 9027

GCD(17, 531) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 931

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

LCM(1, 931) = 931

GCD(1, 931) = ( 1 x 931 ) / 931

GCD(1, 931) = 931 / 931

GCD(1, 931) = 1

GCD of 731, 289, 531, 931 is 1
