Therefore, GCD of numbers 120, 485, 607, 447 is 1

Given Input Data is 120, 485, 607, 447

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

Prime Factorization of 120 is 2 x 2 x 2 x 3 x 5

Prime Factorization of 485 is 5 x 97

Prime Factorization of 607 is 607

Prime Factorization of 447 is 3 x 149

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(120, 485) = 11640

GCD(120, 485) = ( 120 x 485 ) / 11640

GCD(120, 485) = 58200 / 11640

GCD(120, 485) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 607

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

LCM(5, 607) = 3035

GCD(5, 607) = ( 5 x 607 ) / 3035

GCD(5, 607) = 3035 / 3035

GCD(5, 607) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 447

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

LCM(1, 447) = 447

GCD(1, 447) = ( 1 x 447 ) / 447

GCD(1, 447) = 447 / 447

GCD(1, 447) = 1

GCD of 120, 485, 607, 447 is 1
