Given Input Data is 656, 304, 623

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

Prime Factorization of 656 is 2 x 2 x 2 x 2 x 41

Prime Factorization of 304 is 2 x 2 x 2 x 2 x 19

Prime Factorization of 623 is 7 x 89

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(656, 304) = 12464

GCD(656, 304) = ( 656 x 304 ) / 12464

GCD(656, 304) = 199424 / 12464

GCD(656, 304) = 16

Step2:

Here we consider the GCD from the above i.e. 16 as first number and the next as 623

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

LCM(16, 623) = 9968

GCD(16, 623) = ( 16 x 623 ) / 9968

GCD(16, 623) = 9968 / 9968

GCD(16, 623) = 1

GCD of 656, 304, 623 is 1
