We found the divisors of 129, 618, 19, 230 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 129, 618, 19, 230 is 1.

Therefore, GCD of numbers 129, 618, 19, 230 is 1

Given Input Data is 129, 618, 19, 230

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

Prime Factorization of 129 is 3 x 43

Prime Factorization of 618 is 2 x 3 x 103

Prime Factorization of 19 is 19

Prime Factorization of 230 is 2 x 5 x 23

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(129, 618) = 26574

GCD(129, 618) = ( 129 x 618 ) / 26574

GCD(129, 618) = 79722 / 26574

GCD(129, 618) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 19

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

LCM(3, 19) = 57

GCD(3, 19) = ( 3 x 19 ) / 57

GCD(3, 19) = 57 / 57

GCD(3, 19) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 230

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

LCM(1, 230) = 230

GCD(1, 230) = ( 1 x 230 ) / 230

GCD(1, 230) = 230 / 230

GCD(1, 230) = 1

GCD of 129, 618, 19, 230 is 1
