Therefore, GCD of numbers 581, 350, 20, 180 is 1

Given Input Data is 581, 350, 20, 180

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

Prime Factorization of 581 is 7 x 83

Prime Factorization of 350 is 2 x 5 x 5 x 7

Prime Factorization of 20 is 2 x 2 x 5

Prime Factorization of 180 is 2 x 2 x 3 x 3 x 5

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(581, 350) = 29050

GCD(581, 350) = ( 581 x 350 ) / 29050

GCD(581, 350) = 203350 / 29050

GCD(581, 350) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 20

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

LCM(7, 20) = 140

GCD(7, 20) = ( 7 x 20 ) / 140

GCD(7, 20) = 140 / 140

GCD(7, 20) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 180

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

LCM(1, 180) = 180

GCD(1, 180) = ( 1 x 180 ) / 180

GCD(1, 180) = 180 / 180

GCD(1, 180) = 1

GCD of 581, 350, 20, 180 is 1
