Given Input Data is 870, 426, 115

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

Prime Factorization of 870 is 2 x 3 x 5 x 29

Prime Factorization of 426 is 2 x 3 x 71

Prime Factorization of 115 is 5 x 23

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(870, 426) = 61770

GCD(870, 426) = ( 870 x 426 ) / 61770

GCD(870, 426) = 370620 / 61770

GCD(870, 426) = 6

Step2:

Here we consider the GCD from the above i.e. 6 as first number and the next as 115

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

LCM(6, 115) = 690

GCD(6, 115) = ( 6 x 115 ) / 690

GCD(6, 115) = 690 / 690

GCD(6, 115) = 1

GCD of 870, 426, 115 is 1
