Given Input Data is 931, 855, 374, 449

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

Prime Factorization of 931 is 7 x 7 x 19

Prime Factorization of 855 is 3 x 3 x 5 x 19

Prime Factorization of 374 is 2 x 11 x 17

Prime Factorization of 449 is 449

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(931, 855) = 41895

GCD(931, 855) = ( 931 x 855 ) / 41895

GCD(931, 855) = 796005 / 41895

GCD(931, 855) = 19

Step2:

Here we consider the GCD from the above i.e. 19 as first number and the next as 374

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

LCM(19, 374) = 7106

GCD(19, 374) = ( 19 x 374 ) / 7106

GCD(19, 374) = 7106 / 7106

GCD(19, 374) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 449

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

LCM(1, 449) = 449

GCD(1, 449) = ( 1 x 449 ) / 449

GCD(1, 449) = 449 / 449

GCD(1, 449) = 1

GCD of 931, 855, 374, 449 is 1
