Therefore, GCD of numbers 439, 397, 690 is 1

Given Input Data is 439, 397, 690

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

Prime Factorization of 439 is 439

Prime Factorization of 397 is 397

Prime Factorization of 690 is 2 x 3 x 5 x 23

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, 397) = 174283

GCD(439, 397) = ( 439 x 397 ) / 174283

GCD(439, 397) = 174283 / 174283

GCD(439, 397) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 690

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

LCM(1, 690) = 690

GCD(1, 690) = ( 1 x 690 ) / 690

GCD(1, 690) = 690 / 690

GCD(1, 690) = 1

GCD of 439, 397, 690 is 1
