Given Input Data is 828, 556, 128, 955

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

Prime Factorization of 828 is 2 x 2 x 3 x 3 x 23

Prime Factorization of 556 is 2 x 2 x 139

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

Prime Factorization of 955 is 5 x 191

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(828, 556) = 115092

GCD(828, 556) = ( 828 x 556 ) / 115092

GCD(828, 556) = 460368 / 115092

GCD(828, 556) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 128

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

LCM(4, 128) = 128

GCD(4, 128) = ( 4 x 128 ) / 128

GCD(4, 128) = 512 / 128

GCD(4, 128) = 4

Step3:

Here we consider the GCD from the above i.e. 4 as first number and the next as 955

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

LCM(4, 955) = 3820

GCD(4, 955) = ( 4 x 955 ) / 3820

GCD(4, 955) = 3820 / 3820

GCD(4, 955) = 1

GCD of 828, 556, 128, 955 is 1
