Therefore, GCD of numbers 395, 570, 709, 681 is 1

Given Input Data is 395, 570, 709, 681

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

Prime Factorization of 395 is 5 x 79

Prime Factorization of 570 is 2 x 3 x 5 x 19

Prime Factorization of 709 is 709

Prime Factorization of 681 is 3 x 227

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(395, 570) = 45030

GCD(395, 570) = ( 395 x 570 ) / 45030

GCD(395, 570) = 225150 / 45030

GCD(395, 570) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 709

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

LCM(5, 709) = 3545

GCD(5, 709) = ( 5 x 709 ) / 3545

GCD(5, 709) = 3545 / 3545

GCD(5, 709) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 681

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

LCM(1, 681) = 681

GCD(1, 681) = ( 1 x 681 ) / 681

GCD(1, 681) = 681 / 681

GCD(1, 681) = 1

GCD of 395, 570, 709, 681 is 1
