Therefore, GCD of numbers 485, 257, 16, 395 is 1

Given Input Data is 485, 257, 16, 395

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

Prime Factorization of 485 is 5 x 97

Prime Factorization of 257 is 257

Prime Factorization of 16 is 2 x 2 x 2 x 2

Prime Factorization of 395 is 5 x 79

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(485, 257) = 124645

GCD(485, 257) = ( 485 x 257 ) / 124645

GCD(485, 257) = 124645 / 124645

GCD(485, 257) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 16

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

LCM(1, 16) = 16

GCD(1, 16) = ( 1 x 16 ) / 16

GCD(1, 16) = 16 / 16

GCD(1, 16) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 395

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

LCM(1, 395) = 395

GCD(1, 395) = ( 1 x 395 ) / 395

GCD(1, 395) = 395 / 395

GCD(1, 395) = 1

GCD of 485, 257, 16, 395 is 1
