Greatest Common Divisior

We found the divisors of 615, 255, 461, 493 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 615, 255, 461, 493 is 1.

Therefore, GCD of numbers 615, 255, 461, 493 is 1

Given Input Data is 615, 255, 461, 493

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

Prime Factorization of 615 is 3 x 5 x 41

Prime Factorization of 255 is 3 x 5 x 17

Prime Factorization of 461 is 461

Prime Factorization of 493 is 17 x 29

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(615, 255) = 10455

GCD(615, 255) = ( 615 x 255 ) / 10455

GCD(615, 255) = 156825 / 10455

GCD(615, 255) = 15

Step2:

Here we consider the GCD from the above i.e. 15 as first number and the next as 461

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

LCM(15, 461) = 6915

GCD(15, 461) = ( 15 x 461 ) / 6915

GCD(15, 461) = 6915 / 6915

GCD(15, 461) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 493

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

LCM(1, 493) = 493

GCD(1, 493) = ( 1 x 493 ) / 493

GCD(1, 493) = 493 / 493

GCD(1, 493) = 1

GCD of 615, 255, 461, 493 is 1
