Given Input Data is 172, 448, 79, 207

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

Prime Factorization of 172 is 2 x 2 x 43

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

Prime Factorization of 79 is 79

Prime Factorization of 207 is 3 x 3 x 23

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(172, 448) = 19264

GCD(172, 448) = ( 172 x 448 ) / 19264

GCD(172, 448) = 77056 / 19264

GCD(172, 448) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 79

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

LCM(4, 79) = 316

GCD(4, 79) = ( 4 x 79 ) / 316

GCD(4, 79) = 316 / 316

GCD(4, 79) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 207

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

LCM(1, 207) = 207

GCD(1, 207) = ( 1 x 207 ) / 207

GCD(1, 207) = 207 / 207

GCD(1, 207) = 1

GCD of 172, 448, 79, 207 is 1
