Therefore, GCD of numbers 328, 924, 861, 609 is 1

Given Input Data is 328, 924, 861, 609

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

Prime Factorization of 328 is 2 x 2 x 2 x 41

Prime Factorization of 924 is 2 x 2 x 3 x 7 x 11

Prime Factorization of 861 is 3 x 7 x 41

Prime Factorization of 609 is 3 x 7 x 29

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(328, 924) = 75768

GCD(328, 924) = ( 328 x 924 ) / 75768

GCD(328, 924) = 303072 / 75768

GCD(328, 924) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 861

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

LCM(4, 861) = 3444

GCD(4, 861) = ( 4 x 861 ) / 3444

GCD(4, 861) = 3444 / 3444

GCD(4, 861) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 609

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

LCM(1, 609) = 609

GCD(1, 609) = ( 1 x 609 ) / 609

GCD(1, 609) = 609 / 609

GCD(1, 609) = 1

GCD of 328, 924, 861, 609 is 1
