Therefore, GCD of numbers 663, 404, 635 is 1

Given Input Data is 663, 404, 635

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

Prime Factorization of 663 is 3 x 13 x 17

Prime Factorization of 404 is 2 x 2 x 101

Prime Factorization of 635 is 5 x 127

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(663, 404) = 267852

GCD(663, 404) = ( 663 x 404 ) / 267852

GCD(663, 404) = 267852 / 267852

GCD(663, 404) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 635

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

LCM(1, 635) = 635

GCD(1, 635) = ( 1 x 635 ) / 635

GCD(1, 635) = 635 / 635

GCD(1, 635) = 1

GCD of 663, 404, 635 is 1
