Therefore, GCD of numbers 439, 942, 30, 663 is 1

Given Input Data is 439, 942, 30, 663

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

Prime Factorization of 439 is 439

Prime Factorization of 942 is 2 x 3 x 157

Prime Factorization of 30 is 2 x 3 x 5

Prime Factorization of 663 is 3 x 13 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(439, 942) = 413538

GCD(439, 942) = ( 439 x 942 ) / 413538

GCD(439, 942) = 413538 / 413538

GCD(439, 942) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 30

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

LCM(1, 30) = 30

GCD(1, 30) = ( 1 x 30 ) / 30

GCD(1, 30) = 30 / 30

GCD(1, 30) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 663

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

LCM(1, 663) = 663

GCD(1, 663) = ( 1 x 663 ) / 663

GCD(1, 663) = 663 / 663

GCD(1, 663) = 1

GCD of 439, 942, 30, 663 is 1
