Given Input Data is 517, 891, 128

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

Prime Factorization of 517 is 11 x 47

Prime Factorization of 891 is 3 x 3 x 3 x 3 x 11

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(517, 891) = 41877

GCD(517, 891) = ( 517 x 891 ) / 41877

GCD(517, 891) = 460647 / 41877

GCD(517, 891) = 11

Step2:

Here we consider the GCD from the above i.e. 11 as first number and the next as 128

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

LCM(11, 128) = 1408

GCD(11, 128) = ( 11 x 128 ) / 1408

GCD(11, 128) = 1408 / 1408

GCD(11, 128) = 1

GCD of 517, 891, 128 is 1
