Given Input Data is 391, 759, 970, 445

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

Prime Factorization of 391 is 17 x 23

Prime Factorization of 759 is 3 x 11 x 23

Prime Factorization of 970 is 2 x 5 x 97

Prime Factorization of 445 is 5 x 89

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(391, 759) = 12903

GCD(391, 759) = ( 391 x 759 ) / 12903

GCD(391, 759) = 296769 / 12903

GCD(391, 759) = 23

Step2:

Here we consider the GCD from the above i.e. 23 as first number and the next as 970

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

LCM(23, 970) = 22310

GCD(23, 970) = ( 23 x 970 ) / 22310

GCD(23, 970) = 22310 / 22310

GCD(23, 970) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 445

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

LCM(1, 445) = 445

GCD(1, 445) = ( 1 x 445 ) / 445

GCD(1, 445) = 445 / 445

GCD(1, 445) = 1

GCD of 391, 759, 970, 445 is 1
