Given Input Data is 168, 462, 19, 555

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

Prime Factorization of 168 is 2 x 2 x 2 x 3 x 7

Prime Factorization of 462 is 2 x 3 x 7 x 11

Prime Factorization of 19 is 19

Prime Factorization of 555 is 3 x 5 x 37

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(168, 462) = 1848

GCD(168, 462) = ( 168 x 462 ) / 1848

GCD(168, 462) = 77616 / 1848

GCD(168, 462) = 42

Step2:

Here we consider the GCD from the above i.e. 42 as first number and the next as 19

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

LCM(42, 19) = 798

GCD(42, 19) = ( 42 x 19 ) / 798

GCD(42, 19) = 798 / 798

GCD(42, 19) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 555

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

LCM(1, 555) = 555

GCD(1, 555) = ( 1 x 555 ) / 555

GCD(1, 555) = 555 / 555

GCD(1, 555) = 1

GCD of 168, 462, 19, 555 is 1
