Given Input Data is 840, 726, 503

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

Prime Factorization of 840 is 2 x 2 x 2 x 3 x 5 x 7

Prime Factorization of 726 is 2 x 3 x 11 x 11

Prime Factorization of 503 is 503

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(840, 726) = 101640

GCD(840, 726) = ( 840 x 726 ) / 101640

GCD(840, 726) = 609840 / 101640

GCD(840, 726) = 6

Step2:

Here we consider the GCD from the above i.e. 6 as first number and the next as 503

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

LCM(6, 503) = 3018

GCD(6, 503) = ( 6 x 503 ) / 3018

GCD(6, 503) = 3018 / 3018

GCD(6, 503) = 1

GCD of 840, 726, 503 is 1
