Therefore, GCD of numbers 439, 435, 620, 487 is 1

Given Input Data is 439, 435, 620, 487

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

Prime Factorization of 439 is 439

Prime Factorization of 435 is 3 x 5 x 29

Prime Factorization of 620 is 2 x 2 x 5 x 31

Prime Factorization of 487 is 487

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(439, 435) = 190965

GCD(439, 435) = ( 439 x 435 ) / 190965

GCD(439, 435) = 190965 / 190965

GCD(439, 435) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 620

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

LCM(1, 620) = 620

GCD(1, 620) = ( 1 x 620 ) / 620

GCD(1, 620) = 620 / 620

GCD(1, 620) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 487

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

LCM(1, 487) = 487

GCD(1, 487) = ( 1 x 487 ) / 487

GCD(1, 487) = 487 / 487

GCD(1, 487) = 1

GCD of 439, 435, 620, 487 is 1
