Given Input Data is 816, 393, 263, 853

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

Prime Factorization of 816 is 2 x 2 x 2 x 2 x 3 x 17

Prime Factorization of 393 is 3 x 131

Prime Factorization of 263 is 263

Prime Factorization of 853 is 853

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(816, 393) = 106896

GCD(816, 393) = ( 816 x 393 ) / 106896

GCD(816, 393) = 320688 / 106896

GCD(816, 393) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 263

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

LCM(3, 263) = 789

GCD(3, 263) = ( 3 x 263 ) / 789

GCD(3, 263) = 789 / 789

GCD(3, 263) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 853

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

LCM(1, 853) = 853

GCD(1, 853) = ( 1 x 853 ) / 853

GCD(1, 853) = 853 / 853

GCD(1, 853) = 1

GCD of 816, 393, 263, 853 is 1
