Therefore, GCD of numbers 511, 399, 73, 872 is 1

Given Input Data is 511, 399, 73, 872

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

Prime Factorization of 511 is 7 x 73

Prime Factorization of 399 is 3 x 7 x 19

Prime Factorization of 73 is 73

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(511, 399) = 29127

GCD(511, 399) = ( 511 x 399 ) / 29127

GCD(511, 399) = 203889 / 29127

GCD(511, 399) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 73

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

LCM(7, 73) = 511

GCD(7, 73) = ( 7 x 73 ) / 511

GCD(7, 73) = 511 / 511

GCD(7, 73) = 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 511, 399, 73, 872 is 1
