Therefore, GCD of numbers 581, 177, 845, 172 is 1

Given Input Data is 581, 177, 845, 172

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

Prime Factorization of 581 is 7 x 83

Prime Factorization of 177 is 3 x 59

Prime Factorization of 845 is 5 x 13 x 13

Prime Factorization of 172 is 2 x 2 x 43

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, 177) = 102837

GCD(581, 177) = ( 581 x 177 ) / 102837

GCD(581, 177) = 102837 / 102837

GCD(581, 177) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 845

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

LCM(1, 845) = 845

GCD(1, 845) = ( 1 x 845 ) / 845

GCD(1, 845) = 845 / 845

GCD(1, 845) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 172

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

LCM(1, 172) = 172

GCD(1, 172) = ( 1 x 172 ) / 172

GCD(1, 172) = 172 / 172

GCD(1, 172) = 1

GCD of 581, 177, 845, 172 is 1
