Given Input Data is 665, 679, 838

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

Prime Factorization of 665 is 5 x 7 x 19

Prime Factorization of 679 is 7 x 97

Prime Factorization of 838 is 2 x 419

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(665, 679) = 64505

GCD(665, 679) = ( 665 x 679 ) / 64505

GCD(665, 679) = 451535 / 64505

GCD(665, 679) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 838

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

LCM(7, 838) = 5866

GCD(7, 838) = ( 7 x 838 ) / 5866

GCD(7, 838) = 5866 / 5866

GCD(7, 838) = 1

GCD of 665, 679, 838 is 1
