Given Input Data is 24, 664, 649, 439

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

Prime Factorization of 24 is 2 x 2 x 2 x 3

Prime Factorization of 664 is 2 x 2 x 2 x 83

Prime Factorization of 649 is 11 x 59

Prime Factorization of 439 is 439

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(24, 664) = 1992

GCD(24, 664) = ( 24 x 664 ) / 1992

GCD(24, 664) = 15936 / 1992

GCD(24, 664) = 8

Step2:

Here we consider the GCD from the above i.e. 8 as first number and the next as 649

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

LCM(8, 649) = 5192

GCD(8, 649) = ( 8 x 649 ) / 5192

GCD(8, 649) = 5192 / 5192

GCD(8, 649) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 439

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

LCM(1, 439) = 439

GCD(1, 439) = ( 1 x 439 ) / 439

GCD(1, 439) = 439 / 439

GCD(1, 439) = 1

GCD of 24, 664, 649, 439 is 1
