Given Input Data is 673, 128, 470

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

Prime Factorization of 673 is 673

Prime Factorization of 128 is 2 x 2 x 2 x 2 x 2 x 2 x 2

Prime Factorization of 470 is 2 x 5 x 47

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(673, 128) = 86144

GCD(673, 128) = ( 673 x 128 ) / 86144

GCD(673, 128) = 86144 / 86144

GCD(673, 128) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 470

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

LCM(1, 470) = 470

GCD(1, 470) = ( 1 x 470 ) / 470

GCD(1, 470) = 470 / 470

GCD(1, 470) = 1

GCD of 673, 128, 470 is 1
