So the Greatest Common Divisior 401, 511, 428 is 1.

Therefore, GCD of numbers 401, 511, 428 is 1

Given Input Data is 401, 511, 428

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

Prime Factorization of 401 is 401

Prime Factorization of 511 is 7 x 73

Prime Factorization of 428 is 2 x 2 x 107

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(401, 511) = 204911

GCD(401, 511) = ( 401 x 511 ) / 204911

GCD(401, 511) = 204911 / 204911

GCD(401, 511) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 428

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

LCM(1, 428) = 428

GCD(1, 428) = ( 1 x 428 ) / 428

GCD(1, 428) = 428 / 428

GCD(1, 428) = 1

GCD of 401, 511, 428 is 1
