Given Input Data is 845, 728, 16, 673

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

Prime Factorization of 845 is 5 x 13 x 13

Prime Factorization of 728 is 2 x 2 x 2 x 7 x 13

Prime Factorization of 16 is 2 x 2 x 2 x 2

Prime Factorization of 673 is 673

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(845, 728) = 47320

GCD(845, 728) = ( 845 x 728 ) / 47320

GCD(845, 728) = 615160 / 47320

GCD(845, 728) = 13

Step2:

Here we consider the GCD from the above i.e. 13 as first number and the next as 16

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

LCM(13, 16) = 208

GCD(13, 16) = ( 13 x 16 ) / 208

GCD(13, 16) = 208 / 208

GCD(13, 16) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 673

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

LCM(1, 673) = 673

GCD(1, 673) = ( 1 x 673 ) / 673

GCD(1, 673) = 673 / 673

GCD(1, 673) = 1

GCD of 845, 728, 16, 673 is 1
