Greatest Common Divisior

We found the divisors of 455, 100, 13, 833 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 455, 100, 13, 833 is 1.

Therefore, GCD of numbers 455, 100, 13, 833 is 1

Given Input Data is 455, 100, 13, 833

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

Prime Factorization of 455 is 5 x 7 x 13

Prime Factorization of 100 is 2 x 2 x 5 x 5

Prime Factorization of 13 is 13

Prime Factorization of 833 is 7 x 7 x 17

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(455, 100) = 9100

GCD(455, 100) = ( 455 x 100 ) / 9100

GCD(455, 100) = 45500 / 9100

GCD(455, 100) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 13

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

LCM(5, 13) = 65

GCD(5, 13) = ( 5 x 13 ) / 65

GCD(5, 13) = 65 / 65

GCD(5, 13) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 833

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

LCM(1, 833) = 833

GCD(1, 833) = ( 1 x 833 ) / 833

GCD(1, 833) = 833 / 833

GCD(1, 833) = 1

GCD of 455, 100, 13, 833 is 1
