Therefore, GCD of numbers 641, 290, 401 is 1

Given Input Data is 641, 290, 401

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

Prime Factorization of 641 is 641

Prime Factorization of 290 is 2 x 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(641, 290) = 185890

GCD(641, 290) = ( 641 x 290 ) / 185890

GCD(641, 290) = 185890 / 185890

GCD(641, 290) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 401

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

LCM(1, 401) = 401

GCD(1, 401) = ( 1 x 401 ) / 401

GCD(1, 401) = 401 / 401

GCD(1, 401) = 1

GCD of 641, 290, 401 is 1
