Therefore, GCD of numbers 330, 145, 401 is 1

Given Input Data is 330, 145, 401

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

Prime Factorization of 330 is 2 x 3 x 5 x 11

Prime Factorization of 145 is 5 x 29

Prime Factorization of 401 is 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(330, 145) = 9570

GCD(330, 145) = ( 330 x 145 ) / 9570

GCD(330, 145) = 47850 / 9570

GCD(330, 145) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 401

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

LCM(5, 401) = 2005

GCD(5, 401) = ( 5 x 401 ) / 2005

GCD(5, 401) = 2005 / 2005

GCD(5, 401) = 1

GCD of 330, 145, 401 is 1
