Given Input Data is 399, 795, 670, 581

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

Prime Factorization of 399 is 3 x 7 x 19

Prime Factorization of 795 is 3 x 5 x 53

Prime Factorization of 670 is 2 x 5 x 67

Prime Factorization of 581 is 7 x 83

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(399, 795) = 105735

GCD(399, 795) = ( 399 x 795 ) / 105735

GCD(399, 795) = 317205 / 105735

GCD(399, 795) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 670

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

LCM(3, 670) = 2010

GCD(3, 670) = ( 3 x 670 ) / 2010

GCD(3, 670) = 2010 / 2010

GCD(3, 670) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 581

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

LCM(1, 581) = 581

GCD(1, 581) = ( 1 x 581 ) / 581

GCD(1, 581) = 581 / 581

GCD(1, 581) = 1

GCD of 399, 795, 670, 581 is 1
