We found the divisors of 255, 659, 238, 664 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 255, 659, 238, 664 is 1.

Therefore, GCD of numbers 255, 659, 238, 664 is 1

Given Input Data is 255, 659, 238, 664

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

Prime Factorization of 255 is 3 x 5 x 17

Prime Factorization of 659 is 659

Prime Factorization of 238 is 2 x 7 x 17

Prime Factorization of 664 is 2 x 2 x 2 x 83

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(255, 659) = 168045

GCD(255, 659) = ( 255 x 659 ) / 168045

GCD(255, 659) = 168045 / 168045

GCD(255, 659) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 238

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

LCM(1, 238) = 238

GCD(1, 238) = ( 1 x 238 ) / 238

GCD(1, 238) = 238 / 238

GCD(1, 238) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 664

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

LCM(1, 664) = 664

GCD(1, 664) = ( 1 x 664 ) / 664

GCD(1, 664) = 664 / 664

GCD(1, 664) = 1

GCD of 255, 659, 238, 664 is 1
