Given Input Data is 213, 168, 804, 287

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

Prime Factorization of 213 is 3 x 71

Prime Factorization of 168 is 2 x 2 x 2 x 3 x 7

Prime Factorization of 804 is 2 x 2 x 3 x 67

Prime Factorization of 287 is 7 x 41

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(213, 168) = 11928

GCD(213, 168) = ( 213 x 168 ) / 11928

GCD(213, 168) = 35784 / 11928

GCD(213, 168) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 804

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

LCM(3, 804) = 804

GCD(3, 804) = ( 3 x 804 ) / 804

GCD(3, 804) = 2412 / 804

GCD(3, 804) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 287

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

LCM(3, 287) = 861

GCD(3, 287) = ( 3 x 287 ) / 861

GCD(3, 287) = 861 / 861

GCD(3, 287) = 1

GCD of 213, 168, 804, 287 is 1
