Therefore, GCD of numbers 130, 970, 64, 397 is 1

Given Input Data is 130, 970, 64, 397

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

Prime Factorization of 130 is 2 x 5 x 13

Prime Factorization of 970 is 2 x 5 x 97

Prime Factorization of 64 is 2 x 2 x 2 x 2 x 2 x 2

Prime Factorization of 397 is 397

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(130, 970) = 12610

GCD(130, 970) = ( 130 x 970 ) / 12610

GCD(130, 970) = 126100 / 12610

GCD(130, 970) = 10

Step2:

Here we consider the GCD from the above i.e. 10 as first number and the next as 64

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

LCM(10, 64) = 320

GCD(10, 64) = ( 10 x 64 ) / 320

GCD(10, 64) = 640 / 320

GCD(10, 64) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 397

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

LCM(2, 397) = 794

GCD(2, 397) = ( 2 x 397 ) / 794

GCD(2, 397) = 794 / 794

GCD(2, 397) = 1

GCD of 130, 970, 64, 397 is 1
