Therefore, GCD of numbers 18, 612, 569, 265 is 1

Given Input Data is 18, 612, 569, 265

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

Prime Factorization of 18 is 2 x 3 x 3

Prime Factorization of 612 is 2 x 2 x 3 x 3 x 17

Prime Factorization of 569 is 569

Prime Factorization of 265 is 5 x 53

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(18, 612) = 612

GCD(18, 612) = ( 18 x 612 ) / 612

GCD(18, 612) = 11016 / 612

GCD(18, 612) = 18

Step2:

Here we consider the GCD from the above i.e. 18 as first number and the next as 569

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

LCM(18, 569) = 10242

GCD(18, 569) = ( 18 x 569 ) / 10242

GCD(18, 569) = 10242 / 10242

GCD(18, 569) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 265

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

LCM(1, 265) = 265

GCD(1, 265) = ( 1 x 265 ) / 265

GCD(1, 265) = 265 / 265

GCD(1, 265) = 1

GCD of 18, 612, 569, 265 is 1
