Therefore, GCD of numbers 405, 444, 889, 836 is 1

Given Input Data is 405, 444, 889, 836

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

Prime Factorization of 405 is 3 x 3 x 3 x 3 x 5

Prime Factorization of 444 is 2 x 2 x 3 x 37

Prime Factorization of 889 is 7 x 127

Prime Factorization of 836 is 2 x 2 x 11 x 19

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(405, 444) = 59940

GCD(405, 444) = ( 405 x 444 ) / 59940

GCD(405, 444) = 179820 / 59940

GCD(405, 444) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 889

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

LCM(3, 889) = 2667

GCD(3, 889) = ( 3 x 889 ) / 2667

GCD(3, 889) = 2667 / 2667

GCD(3, 889) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 836

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

LCM(1, 836) = 836

GCD(1, 836) = ( 1 x 836 ) / 836

GCD(1, 836) = 836 / 836

GCD(1, 836) = 1

GCD of 405, 444, 889, 836 is 1
