Given Input Data is 639, 111, 448, 511

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

Prime Factorization of 639 is 3 x 3 x 71

Prime Factorization of 111 is 3 x 37

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

Prime Factorization of 511 is 7 x 73

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(639, 111) = 23643

GCD(639, 111) = ( 639 x 111 ) / 23643

GCD(639, 111) = 70929 / 23643

GCD(639, 111) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 448

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

LCM(3, 448) = 1344

GCD(3, 448) = ( 3 x 448 ) / 1344

GCD(3, 448) = 1344 / 1344

GCD(3, 448) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 511

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

LCM(1, 511) = 511

GCD(1, 511) = ( 1 x 511 ) / 511

GCD(1, 511) = 511 / 511

GCD(1, 511) = 1

GCD of 639, 111, 448, 511 is 1
