1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
Greatest Common Divisior
We found the divisors of 209, 258, 390 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 209, 258, 390 is 1.
Therefore, GCD of numbers 209, 258, 390 is 1
Given Input Data is 209, 258, 390
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 209 is 11 x 19
Prime Factorization of 258 is 2 x 3 x 43
Prime Factorization of 390 is 2 x 3 x 5 x 13
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(209, 258) = 53922
GCD(209, 258) = ( 209 x 258 ) / 53922
GCD(209, 258) = 53922 / 53922
GCD(209, 258) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 390
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 390) = 390
GCD(1, 390) = ( 1 x 390 ) / 390
GCD(1, 390) = 390 / 390
GCD(1, 390) = 1
GCD of 209, 258, 390 is 1
