Therefore, GCD of numbers 445, 477, 665 is 1

Given Input Data is 445, 477, 665

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

Prime Factorization of 445 is 5 x 89

Prime Factorization of 477 is 3 x 3 x 53

Prime Factorization of 665 is 5 x 7 x 19

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(445, 477) = 212265

GCD(445, 477) = ( 445 x 477 ) / 212265

GCD(445, 477) = 212265 / 212265

GCD(445, 477) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 665

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

LCM(1, 665) = 665

GCD(1, 665) = ( 1 x 665 ) / 665

GCD(1, 665) = 665 / 665

GCD(1, 665) = 1

GCD of 445, 477, 665 is 1
