Given Input Data is 28, 448, 839, 451

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 448 is 2 x 2 x 2 x 2 x 2 x 2 x 7

Prime Factorization of 839 is 839

Prime Factorization of 451 is 11 x 41

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, 448) = 448

GCD(28, 448) = ( 28 x 448 ) / 448

GCD(28, 448) = 12544 / 448

GCD(28, 448) = 28

Step2:

Here we consider the GCD from the above i.e. 28 as first number and the next as 839

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

LCM(28, 839) = 23492

GCD(28, 839) = ( 28 x 839 ) / 23492

GCD(28, 839) = 23492 / 23492

GCD(28, 839) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 451

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

LCM(1, 451) = 451

GCD(1, 451) = ( 1 x 451 ) / 451

GCD(1, 451) = 451 / 451

GCD(1, 451) = 1

GCD of 28, 448, 839, 451 is 1
