Given Input Data is 855, 505, 404, 130

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

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

Prime Factorization of 505 is 5 x 101

Prime Factorization of 404 is 2 x 2 x 101

Prime Factorization of 130 is 2 x 5 x 13

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(855, 505) = 86355

GCD(855, 505) = ( 855 x 505 ) / 86355

GCD(855, 505) = 431775 / 86355

GCD(855, 505) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 404

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

LCM(5, 404) = 2020

GCD(5, 404) = ( 5 x 404 ) / 2020

GCD(5, 404) = 2020 / 2020

GCD(5, 404) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 130

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

LCM(1, 130) = 130

GCD(1, 130) = ( 1 x 130 ) / 130

GCD(1, 130) = 130 / 130

GCD(1, 130) = 1

GCD of 855, 505, 404, 130 is 1
