Given Input Data is 663, 321, 12, 895

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

Prime Factorization of 663 is 3 x 13 x 17

Prime Factorization of 321 is 3 x 107

Prime Factorization of 12 is 2 x 2 x 3

Prime Factorization of 895 is 5 x 179

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(663, 321) = 70941

GCD(663, 321) = ( 663 x 321 ) / 70941

GCD(663, 321) = 212823 / 70941

GCD(663, 321) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 12

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

LCM(3, 12) = 12

GCD(3, 12) = ( 3 x 12 ) / 12

GCD(3, 12) = 36 / 12

GCD(3, 12) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 895

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

LCM(3, 895) = 2685

GCD(3, 895) = ( 3 x 895 ) / 2685

GCD(3, 895) = 2685 / 2685

GCD(3, 895) = 1

GCD of 663, 321, 12, 895 is 1
