Given Input Data is 128, 560, 68, 935

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

Prime Factorization of 128 is 2 x 2 x 2 x 2 x 2 x 2 x 2

Prime Factorization of 560 is 2 x 2 x 2 x 2 x 5 x 7

Prime Factorization of 68 is 2 x 2 x 17

Prime Factorization of 935 is 5 x 11 x 17

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(128, 560) = 4480

GCD(128, 560) = ( 128 x 560 ) / 4480

GCD(128, 560) = 71680 / 4480

GCD(128, 560) = 16

Step2:

Here we consider the GCD from the above i.e. 16 as first number and the next as 68

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

LCM(16, 68) = 272

GCD(16, 68) = ( 16 x 68 ) / 272

GCD(16, 68) = 1088 / 272

GCD(16, 68) = 4

Step3:

Here we consider the GCD from the above i.e. 4 as first number and the next as 935

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

LCM(4, 935) = 3740

GCD(4, 935) = ( 4 x 935 ) / 3740

GCD(4, 935) = 3740 / 3740

GCD(4, 935) = 1

GCD of 128, 560, 68, 935 is 1
