Therefore, GCD of numbers 30, 609, 487, 612 is 1

Given Input Data is 30, 609, 487, 612

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

Prime Factorization of 30 is 2 x 3 x 5

Prime Factorization of 609 is 3 x 7 x 29

Prime Factorization of 487 is 487

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

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(30, 609) = 6090

GCD(30, 609) = ( 30 x 609 ) / 6090

GCD(30, 609) = 18270 / 6090

GCD(30, 609) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 487

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

LCM(3, 487) = 1461

GCD(3, 487) = ( 3 x 487 ) / 1461

GCD(3, 487) = 1461 / 1461

GCD(3, 487) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 612

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

LCM(1, 612) = 612

GCD(1, 612) = ( 1 x 612 ) / 612

GCD(1, 612) = 612 / 612

GCD(1, 612) = 1

GCD of 30, 609, 487, 612 is 1
