Given Input Data is 161, 448, 447, 487

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

Prime Factorization of 161 is 7 x 23

Prime Factorization of 448 is 2 x 2 x 2 x 2 x 2 x 2 x 7

Prime Factorization of 447 is 3 x 149

Prime Factorization of 487 is 487

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(161, 448) = 10304

GCD(161, 448) = ( 161 x 448 ) / 10304

GCD(161, 448) = 72128 / 10304

GCD(161, 448) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 447

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

LCM(7, 447) = 3129

GCD(7, 447) = ( 7 x 447 ) / 3129

GCD(7, 447) = 3129 / 3129

GCD(7, 447) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 487

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

LCM(1, 487) = 487

GCD(1, 487) = ( 1 x 487 ) / 487

GCD(1, 487) = 487 / 487

GCD(1, 487) = 1

GCD of 161, 448, 447, 487 is 1
