Given Input Data is 868, 812, 67, 856

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

Prime Factorization of 868 is 2 x 2 x 7 x 31

Prime Factorization of 812 is 2 x 2 x 7 x 29

Prime Factorization of 67 is 67

Prime Factorization of 856 is 2 x 2 x 2 x 107

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(868, 812) = 25172

GCD(868, 812) = ( 868 x 812 ) / 25172

GCD(868, 812) = 704816 / 25172

GCD(868, 812) = 28

Step2:

Here we consider the GCD from the above i.e. 28 as first number and the next as 67

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

LCM(28, 67) = 1876

GCD(28, 67) = ( 28 x 67 ) / 1876

GCD(28, 67) = 1876 / 1876

GCD(28, 67) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 856

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

LCM(1, 856) = 856

GCD(1, 856) = ( 1 x 856 ) / 856

GCD(1, 856) = 856 / 856

GCD(1, 856) = 1

GCD of 868, 812, 67, 856 is 1
