Given Input Data is 280, 238, 56, 605

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

Prime Factorization of 280 is 2 x 2 x 2 x 5 x 7

Prime Factorization of 238 is 2 x 7 x 17

Prime Factorization of 56 is 2 x 2 x 2 x 7

Prime Factorization of 605 is 5 x 11 x 11

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(280, 238) = 4760

GCD(280, 238) = ( 280 x 238 ) / 4760

GCD(280, 238) = 66640 / 4760

GCD(280, 238) = 14

Step2:

Here we consider the GCD from the above i.e. 14 as first number and the next as 56

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

LCM(14, 56) = 56

GCD(14, 56) = ( 14 x 56 ) / 56

GCD(14, 56) = 784 / 56

GCD(14, 56) = 14

Step3:

Here we consider the GCD from the above i.e. 14 as first number and the next as 605

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

LCM(14, 605) = 8470

GCD(14, 605) = ( 14 x 605 ) / 8470

GCD(14, 605) = 8470 / 8470

GCD(14, 605) = 1

GCD of 280, 238, 56, 605 is 1
