Given Input Data is 105, 711, 836, 865

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

Prime Factorization of 105 is 3 x 5 x 7

Prime Factorization of 711 is 3 x 3 x 79

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

Prime Factorization of 865 is 5 x 173

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(105, 711) = 24885

GCD(105, 711) = ( 105 x 711 ) / 24885

GCD(105, 711) = 74655 / 24885

GCD(105, 711) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 836

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

LCM(3, 836) = 2508

GCD(3, 836) = ( 3 x 836 ) / 2508

GCD(3, 836) = 2508 / 2508

GCD(3, 836) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 865

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

LCM(1, 865) = 865

GCD(1, 865) = ( 1 x 865 ) / 865

GCD(1, 865) = 865 / 865

GCD(1, 865) = 1

GCD of 105, 711, 836, 865 is 1
