Greatest Common Divisior

We found the divisors of 19, 210, 385, 554 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 19, 210, 385, 554 is 1.

Therefore, GCD of numbers 19, 210, 385, 554 is 1

Given Input Data is 19, 210, 385, 554

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

Prime Factorization of 19 is 19

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

Prime Factorization of 385 is 5 x 7 x 11

Prime Factorization of 554 is 2 x 277

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(19, 210) = 3990

GCD(19, 210) = ( 19 x 210 ) / 3990

GCD(19, 210) = 3990 / 3990

GCD(19, 210) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 385

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

LCM(1, 385) = 385

GCD(1, 385) = ( 1 x 385 ) / 385

GCD(1, 385) = 385 / 385

GCD(1, 385) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 554

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

LCM(1, 554) = 554

GCD(1, 554) = ( 1 x 554 ) / 554

GCD(1, 554) = 554 / 554

GCD(1, 554) = 1

GCD of 19, 210, 385, 554 is 1
