Therefore, GCD of numbers 430, 205, 76, 872 is 1

Given Input Data is 430, 205, 76, 872

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

Prime Factorization of 430 is 2 x 5 x 43

Prime Factorization of 205 is 5 x 41

Prime Factorization of 76 is 2 x 2 x 19

Prime Factorization of 872 is 2 x 2 x 2 x 109

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(430, 205) = 17630

GCD(430, 205) = ( 430 x 205 ) / 17630

GCD(430, 205) = 88150 / 17630

GCD(430, 205) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 76

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

LCM(5, 76) = 380

GCD(5, 76) = ( 5 x 76 ) / 380

GCD(5, 76) = 380 / 380

GCD(5, 76) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 872

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

LCM(1, 872) = 872

GCD(1, 872) = ( 1 x 872 ) / 872

GCD(1, 872) = 872 / 872

GCD(1, 872) = 1

GCD of 430, 205, 76, 872 is 1
