Given Input Data is 520, 472, 249, 607

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

Prime Factorization of 520 is 2 x 2 x 2 x 5 x 13

Prime Factorization of 472 is 2 x 2 x 2 x 59

Prime Factorization of 249 is 3 x 83

Prime Factorization of 607 is 607

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(520, 472) = 30680

GCD(520, 472) = ( 520 x 472 ) / 30680

GCD(520, 472) = 245440 / 30680

GCD(520, 472) = 8

Step2:

Here we consider the GCD from the above i.e. 8 as first number and the next as 249

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

LCM(8, 249) = 1992

GCD(8, 249) = ( 8 x 249 ) / 1992

GCD(8, 249) = 1992 / 1992

GCD(8, 249) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 607

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

LCM(1, 607) = 607

GCD(1, 607) = ( 1 x 607 ) / 607

GCD(1, 607) = 607 / 607

GCD(1, 607) = 1

GCD of 520, 472, 249, 607 is 1
