We found the divisors of 169, 255, 191, 730 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 169, 255, 191, 730 is 1.

Therefore, GCD of numbers 169, 255, 191, 730 is 1

Given Input Data is 169, 255, 191, 730

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

Prime Factorization of 169 is 13 x 13

Prime Factorization of 255 is 3 x 5 x 17

Prime Factorization of 191 is 191

Prime Factorization of 730 is 2 x 5 x 73

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(169, 255) = 43095

GCD(169, 255) = ( 169 x 255 ) / 43095

GCD(169, 255) = 43095 / 43095

GCD(169, 255) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 191

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

LCM(1, 191) = 191

GCD(1, 191) = ( 1 x 191 ) / 191

GCD(1, 191) = 191 / 191

GCD(1, 191) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 730

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

LCM(1, 730) = 730

GCD(1, 730) = ( 1 x 730 ) / 730

GCD(1, 730) = 730 / 730

GCD(1, 730) = 1

GCD of 169, 255, 191, 730 is 1
