Therefore, GCD of numbers 385, 530, 631 is 1

Given Input Data is 385, 530, 631

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

Prime Factorization of 385 is 5 x 7 x 11

Prime Factorization of 530 is 2 x 5 x 53

Prime Factorization of 631 is 631

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(385, 530) = 40810

GCD(385, 530) = ( 385 x 530 ) / 40810

GCD(385, 530) = 204050 / 40810

GCD(385, 530) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 631

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

LCM(5, 631) = 3155

GCD(5, 631) = ( 5 x 631 ) / 3155

GCD(5, 631) = 3155 / 3155

GCD(5, 631) = 1

GCD of 385, 530, 631 is 1
