Therefore, GCD of numbers 209, 539, 615, 323 is 1

Given Input Data is 209, 539, 615, 323

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

Prime Factorization of 209 is 11 x 19

Prime Factorization of 539 is 7 x 7 x 11

Prime Factorization of 615 is 3 x 5 x 41

Prime Factorization of 323 is 17 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(209, 539) = 10241

GCD(209, 539) = ( 209 x 539 ) / 10241

GCD(209, 539) = 112651 / 10241

GCD(209, 539) = 11

Step2:

Here we consider the GCD from the above i.e. 11 as first number and the next as 615

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

LCM(11, 615) = 6765

GCD(11, 615) = ( 11 x 615 ) / 6765

GCD(11, 615) = 6765 / 6765

GCD(11, 615) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 323

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

LCM(1, 323) = 323

GCD(1, 323) = ( 1 x 323 ) / 323

GCD(1, 323) = 323 / 323

GCD(1, 323) = 1

GCD of 209, 539, 615, 323 is 1
