Given Input Data is 980, 726, 389, 209

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

Prime Factorization of 980 is 2 x 2 x 5 x 7 x 7

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

Prime Factorization of 389 is 389

Prime Factorization of 209 is 11 x 19

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(980, 726) = 355740

GCD(980, 726) = ( 980 x 726 ) / 355740

GCD(980, 726) = 711480 / 355740

GCD(980, 726) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 389

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

LCM(2, 389) = 778

GCD(2, 389) = ( 2 x 389 ) / 778

GCD(2, 389) = 778 / 778

GCD(2, 389) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 209

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

LCM(1, 209) = 209

GCD(1, 209) = ( 1 x 209 ) / 209

GCD(1, 209) = 209 / 209

GCD(1, 209) = 1

GCD of 980, 726, 389, 209 is 1
