Therefore, GCD of numbers 351, 387, 389 is 1

Given Input Data is 351, 387, 389

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

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

Prime Factorization of 387 is 3 x 3 x 43

Prime Factorization of 389 is 389

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(351, 387) = 15093

GCD(351, 387) = ( 351 x 387 ) / 15093

GCD(351, 387) = 135837 / 15093

GCD(351, 387) = 9

Step2:

Here we consider the GCD from the above i.e. 9 as first number and the next as 389

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

LCM(9, 389) = 3501

GCD(9, 389) = ( 9 x 389 ) / 3501

GCD(9, 389) = 3501 / 3501

GCD(9, 389) = 1

GCD of 351, 387, 389 is 1
