Given Input Data is 28, 604, 456, 631

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

Prime Factorization of 28 is 2 x 2 x 7

Prime Factorization of 604 is 2 x 2 x 151

Prime Factorization of 456 is 2 x 2 x 2 x 3 x 19

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(28, 604) = 4228

GCD(28, 604) = ( 28 x 604 ) / 4228

GCD(28, 604) = 16912 / 4228

GCD(28, 604) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 456

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

LCM(4, 456) = 456

GCD(4, 456) = ( 4 x 456 ) / 456

GCD(4, 456) = 1824 / 456

GCD(4, 456) = 4

Step3:

Here we consider the GCD from the above i.e. 4 as first number and the next as 631

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

LCM(4, 631) = 2524

GCD(4, 631) = ( 4 x 631 ) / 2524

GCD(4, 631) = 2524 / 2524

GCD(4, 631) = 1

GCD of 28, 604, 456, 631 is 1
