Given Input Data is 666, 348, 128, 287

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

Prime Factorization of 666 is 2 x 3 x 3 x 37

Prime Factorization of 348 is 2 x 2 x 3 x 29

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

Prime Factorization of 287 is 7 x 41

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(666, 348) = 38628

GCD(666, 348) = ( 666 x 348 ) / 38628

GCD(666, 348) = 231768 / 38628

GCD(666, 348) = 6

Step2:

Here we consider the GCD from the above i.e. 6 as first number and the next as 128

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

LCM(6, 128) = 384

GCD(6, 128) = ( 6 x 128 ) / 384

GCD(6, 128) = 768 / 384

GCD(6, 128) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 287

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

LCM(2, 287) = 574

GCD(2, 287) = ( 2 x 287 ) / 574

GCD(2, 287) = 574 / 574

GCD(2, 287) = 1

GCD of 666, 348, 128, 287 is 1
