Given Input Data is 875, 420, 24, 128

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

Prime Factorization of 875 is 5 x 5 x 5 x 7

Prime Factorization of 420 is 2 x 2 x 3 x 5 x 7

Prime Factorization of 24 is 2 x 2 x 2 x 3

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

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(875, 420) = 10500

GCD(875, 420) = ( 875 x 420 ) / 10500

GCD(875, 420) = 367500 / 10500

GCD(875, 420) = 35

Step2:

Here we consider the GCD from the above i.e. 35 as first number and the next as 24

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

LCM(35, 24) = 840

GCD(35, 24) = ( 35 x 24 ) / 840

GCD(35, 24) = 840 / 840

GCD(35, 24) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 128

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

LCM(1, 128) = 128

GCD(1, 128) = ( 1 x 128 ) / 128

GCD(1, 128) = 128 / 128

GCD(1, 128) = 1

GCD of 875, 420, 24, 128 is 1
