Given Input Data is 407, 451, 260, 824

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

Prime Factorization of 407 is 11 x 37

Prime Factorization of 451 is 11 x 41

Prime Factorization of 260 is 2 x 2 x 5 x 13

Prime Factorization of 824 is 2 x 2 x 2 x 103

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(407, 451) = 16687

GCD(407, 451) = ( 407 x 451 ) / 16687

GCD(407, 451) = 183557 / 16687

GCD(407, 451) = 11

Step2:

Here we consider the GCD from the above i.e. 11 as first number and the next as 260

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

LCM(11, 260) = 2860

GCD(11, 260) = ( 11 x 260 ) / 2860

GCD(11, 260) = 2860 / 2860

GCD(11, 260) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 824

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

LCM(1, 824) = 824

GCD(1, 824) = ( 1 x 824 ) / 824

GCD(1, 824) = 824 / 824

GCD(1, 824) = 1

GCD of 407, 451, 260, 824 is 1
