Greatest Common Divisior

We found the divisors of 213, 220, 47, 418 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 213, 220, 47, 418 is 1.

Therefore, GCD of numbers 213, 220, 47, 418 is 1

Given Input Data is 213, 220, 47, 418

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

Prime Factorization of 213 is 3 x 71

Prime Factorization of 220 is 2 x 2 x 5 x 11

Prime Factorization of 47 is 47

Prime Factorization of 418 is 2 x 11 x 19

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(213, 220) = 46860

GCD(213, 220) = ( 213 x 220 ) / 46860

GCD(213, 220) = 46860 / 46860

GCD(213, 220) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 47

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

LCM(1, 47) = 47

GCD(1, 47) = ( 1 x 47 ) / 47

GCD(1, 47) = 47 / 47

GCD(1, 47) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 418

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

LCM(1, 418) = 418

GCD(1, 418) = ( 1 x 418 ) / 418

GCD(1, 418) = 418 / 418

GCD(1, 418) = 1

GCD of 213, 220, 47, 418 is 1
