Therefore, GCD of numbers 485, 389, 42, 425 is 1

Given Input Data is 485, 389, 42, 425

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

Prime Factorization of 485 is 5 x 97

Prime Factorization of 389 is 389

Prime Factorization of 42 is 2 x 3 x 7

Prime Factorization of 425 is 5 x 5 x 17

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(485, 389) = 188665

GCD(485, 389) = ( 485 x 389 ) / 188665

GCD(485, 389) = 188665 / 188665

GCD(485, 389) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 42

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

LCM(1, 42) = 42

GCD(1, 42) = ( 1 x 42 ) / 42

GCD(1, 42) = 42 / 42

GCD(1, 42) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 425

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

LCM(1, 425) = 425

GCD(1, 425) = ( 1 x 425 ) / 425

GCD(1, 425) = 425 / 425

GCD(1, 425) = 1

GCD of 485, 389, 42, 425 is 1
