Therefore, GCD of numbers 12, 162, 237, 865 is 1

Given Input Data is 12, 162, 237, 865

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

Prime Factorization of 12 is 2 x 2 x 3

Prime Factorization of 162 is 2 x 3 x 3 x 3 x 3

Prime Factorization of 237 is 3 x 79

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(12, 162) = 324

GCD(12, 162) = ( 12 x 162 ) / 324

GCD(12, 162) = 1944 / 324

GCD(12, 162) = 6

Step2:

Here we consider the GCD from the above i.e. 6 as first number and the next as 237

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

LCM(6, 237) = 474

GCD(6, 237) = ( 6 x 237 ) / 474

GCD(6, 237) = 1422 / 474

GCD(6, 237) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 865

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

LCM(3, 865) = 2595

GCD(3, 865) = ( 3 x 865 ) / 2595

GCD(3, 865) = 2595 / 2595

GCD(3, 865) = 1

GCD of 12, 162, 237, 865 is 1
