Therefore, GCD of numbers 815, 351, 802 is 1

Given Input Data is 815, 351, 802

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

Prime Factorization of 815 is 5 x 163

Prime Factorization of 351 is 3 x 3 x 3 x 13

Prime Factorization of 802 is 2 x 401

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, 351) = 286065

GCD(815, 351) = ( 815 x 351 ) / 286065

GCD(815, 351) = 286065 / 286065

GCD(815, 351) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 802

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

LCM(1, 802) = 802

GCD(1, 802) = ( 1 x 802 ) / 802

GCD(1, 802) = 802 / 802

GCD(1, 802) = 1

GCD of 815, 351, 802 is 1
