We found the divisors of 210, 103, 289, 399 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 210, 103, 289, 399 is 1.

Therefore, GCD of numbers 210, 103, 289, 399 is 1

Given Input Data is 210, 103, 289, 399

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

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

Prime Factorization of 103 is 103

Prime Factorization of 289 is 17 x 17

Prime Factorization of 399 is 3 x 7 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(210, 103) = 21630

GCD(210, 103) = ( 210 x 103 ) / 21630

GCD(210, 103) = 21630 / 21630

GCD(210, 103) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 289

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

LCM(1, 289) = 289

GCD(1, 289) = ( 1 x 289 ) / 289

GCD(1, 289) = 289 / 289

GCD(1, 289) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 399

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

LCM(1, 399) = 399

GCD(1, 399) = ( 1 x 399 ) / 399

GCD(1, 399) = 399 / 399

GCD(1, 399) = 1

GCD of 210, 103, 289, 399 is 1
