Therefore, GCD of numbers 439, 191, 31, 678 is 1

Given Input Data is 439, 191, 31, 678

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

Prime Factorization of 439 is 439

Prime Factorization of 191 is 191

Prime Factorization of 31 is 31

Prime Factorization of 678 is 2 x 3 x 113

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, 191) = 83849

GCD(439, 191) = ( 439 x 191 ) / 83849

GCD(439, 191) = 83849 / 83849

GCD(439, 191) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 31

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

LCM(1, 31) = 31

GCD(1, 31) = ( 1 x 31 ) / 31

GCD(1, 31) = 31 / 31

GCD(1, 31) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 678

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

LCM(1, 678) = 678

GCD(1, 678) = ( 1 x 678 ) / 678

GCD(1, 678) = 678 / 678

GCD(1, 678) = 1

GCD of 439, 191, 31, 678 is 1
