Therefore, GCD of numbers 397, 664, 530 is 1

Given Input Data is 397, 664, 530

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

Prime Factorization of 397 is 397

Prime Factorization of 664 is 2 x 2 x 2 x 83

Prime Factorization of 530 is 2 x 5 x 53

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(397, 664) = 263608

GCD(397, 664) = ( 397 x 664 ) / 263608

GCD(397, 664) = 263608 / 263608

GCD(397, 664) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 530

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

LCM(1, 530) = 530

GCD(1, 530) = ( 1 x 530 ) / 530

GCD(1, 530) = 530 / 530

GCD(1, 530) = 1

GCD of 397, 664, 530 is 1
