Therefore, GCD of numbers 720, 363, 418, 186 is 1

Given Input Data is 720, 363, 418, 186

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 363 is 3 x 11 x 11

Prime Factorization of 418 is 2 x 11 x 19

Prime Factorization of 186 is 2 x 3 x 31

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, 363) = 87120

GCD(720, 363) = ( 720 x 363 ) / 87120

GCD(720, 363) = 261360 / 87120

GCD(720, 363) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 418

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

LCM(3, 418) = 1254

GCD(3, 418) = ( 3 x 418 ) / 1254

GCD(3, 418) = 1254 / 1254

GCD(3, 418) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 186

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

LCM(1, 186) = 186

GCD(1, 186) = ( 1 x 186 ) / 186

GCD(1, 186) = 186 / 186

GCD(1, 186) = 1

GCD of 720, 363, 418, 186 is 1
