Greatest Common Divisior

We found the divisors of 301, 210, 18, 668 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 301, 210, 18, 668 is 1.

Therefore, GCD of numbers 301, 210, 18, 668 is 1

Given Input Data is 301, 210, 18, 668

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

Prime Factorization of 301 is 7 x 43

Prime Factorization of 210 is 2 x 3 x 5 x 7

Prime Factorization of 18 is 2 x 3 x 3

Prime Factorization of 668 is 2 x 2 x 167

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(301, 210) = 9030

GCD(301, 210) = ( 301 x 210 ) / 9030

GCD(301, 210) = 63210 / 9030

GCD(301, 210) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 18

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

LCM(7, 18) = 126

GCD(7, 18) = ( 7 x 18 ) / 126

GCD(7, 18) = 126 / 126

GCD(7, 18) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 668

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

LCM(1, 668) = 668

GCD(1, 668) = ( 1 x 668 ) / 668

GCD(1, 668) = 668 / 668

GCD(1, 668) = 1

GCD of 301, 210, 18, 668 is 1
