Therefore, GCD of numbers 395, 455, 174, 172 is 1

Given Input Data is 395, 455, 174, 172

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

Prime Factorization of 395 is 5 x 79

Prime Factorization of 455 is 5 x 7 x 13

Prime Factorization of 174 is 2 x 3 x 29

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(395, 455) = 35945

GCD(395, 455) = ( 395 x 455 ) / 35945

GCD(395, 455) = 179725 / 35945

GCD(395, 455) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 174

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

LCM(5, 174) = 870

GCD(5, 174) = ( 5 x 174 ) / 870

GCD(5, 174) = 870 / 870

GCD(5, 174) = 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 395, 455, 174, 172 is 1
