Given Input Data is 197, 826, 688, 806

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

Prime Factorization of 197 is 197

Prime Factorization of 826 is 2 x 7 x 59

Prime Factorization of 688 is 2 x 2 x 2 x 2 x 43

Prime Factorization of 806 is 2 x 13 x 31

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(197, 826) = 162722

GCD(197, 826) = ( 197 x 826 ) / 162722

GCD(197, 826) = 162722 / 162722

GCD(197, 826) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 688

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

LCM(1, 688) = 688

GCD(1, 688) = ( 1 x 688 ) / 688

GCD(1, 688) = 688 / 688

GCD(1, 688) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 806

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

LCM(1, 806) = 806

GCD(1, 806) = ( 1 x 806 ) / 806

GCD(1, 806) = 806 / 806

GCD(1, 806) = 1

GCD of 197, 826, 688, 806 is 1
