Finding GCD of 401, 491, 641 using Prime Factorization

Given Input Data is 401, 491, 641

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

Prime Factorization of 401 is 401

Prime Factorization of 491 is 491

Prime Factorization of 641 is 641

The above numbers do not have any common prime factor. So GCD is 1

Finding GCD of 401, 491, 641 using LCM Formula

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(401, 491) = 196891

GCD(401, 491) = ( 401 x 491 ) / 196891

GCD(401, 491) = 196891 / 196891

GCD(401, 491) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 641

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

LCM(1, 641) = 641

GCD(1, 641) = ( 1 x 641 ) / 641

GCD(1, 641) = 641 / 641

GCD(1, 641) = 1

GCD of 401, 491, 641 is 1
