Therefore, GCD of numbers 49, 329, 663, 631 is 1

Given Input Data is 49, 329, 663, 631

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

Prime Factorization of 49 is 7 x 7

Prime Factorization of 329 is 7 x 47

Prime Factorization of 663 is 3 x 13 x 17

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(49, 329) = 2303

GCD(49, 329) = ( 49 x 329 ) / 2303

GCD(49, 329) = 16121 / 2303

GCD(49, 329) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 663

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

LCM(7, 663) = 4641

GCD(7, 663) = ( 7 x 663 ) / 4641

GCD(7, 663) = 4641 / 4641

GCD(7, 663) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 631

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

LCM(1, 631) = 631

GCD(1, 631) = ( 1 x 631 ) / 631

GCD(1, 631) = 631 / 631

GCD(1, 631) = 1

GCD of 49, 329, 663, 631 is 1
