Given Input Data is 815, 385, 959

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

Prime Factorization of 815 is 5 x 163

Prime Factorization of 385 is 5 x 7 x 11

Prime Factorization of 959 is 7 x 137

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(815, 385) = 62755

GCD(815, 385) = ( 815 x 385 ) / 62755

GCD(815, 385) = 313775 / 62755

GCD(815, 385) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 959

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

LCM(5, 959) = 4795

GCD(5, 959) = ( 5 x 959 ) / 4795

GCD(5, 959) = 4795 / 4795

GCD(5, 959) = 1

GCD of 815, 385, 959 is 1
