Therefore, GCD of numbers 720, 180, 605, 363 is 1

Given Input Data is 720, 180, 605, 363

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

Prime Factorization of 720 is 2 x 2 x 2 x 2 x 3 x 3 x 5

Prime Factorization of 180 is 2 x 2 x 3 x 3 x 5

Prime Factorization of 605 is 5 x 11 x 11

Prime Factorization of 363 is 3 x 11 x 11

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(720, 180) = 720

GCD(720, 180) = ( 720 x 180 ) / 720

GCD(720, 180) = 129600 / 720

GCD(720, 180) = 180

Step2:

Here we consider the GCD from the above i.e. 180 as first number and the next as 605

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

LCM(180, 605) = 21780

GCD(180, 605) = ( 180 x 605 ) / 21780

GCD(180, 605) = 108900 / 21780

GCD(180, 605) = 5

Step3:

Here we consider the GCD from the above i.e. 5 as first number and the next as 363

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

LCM(5, 363) = 1815

GCD(5, 363) = ( 5 x 363 ) / 1815

GCD(5, 363) = 1815 / 1815

GCD(5, 363) = 1

GCD of 720, 180, 605, 363 is 1
