Given Input Data is 671, 917, 128

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

Prime Factorization of 671 is 11 x 61

Prime Factorization of 917 is 7 x 131

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(671, 917) = 615307

GCD(671, 917) = ( 671 x 917 ) / 615307

GCD(671, 917) = 615307 / 615307

GCD(671, 917) = 1

Step2:

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 671, 917, 128 is 1
