Greatest Common Divisior

We found the divisors of 30, 629, 657, 604 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 30, 629, 657, 604 is 1.

Therefore, GCD of numbers 30, 629, 657, 604 is 1

Given Input Data is 30, 629, 657, 604

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

Prime Factorization of 30 is 2 x 3 x 5

Prime Factorization of 629 is 17 x 37

Prime Factorization of 657 is 3 x 3 x 73

Prime Factorization of 604 is 2 x 2 x 151

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(30, 629) = 18870

GCD(30, 629) = ( 30 x 629 ) / 18870

GCD(30, 629) = 18870 / 18870

GCD(30, 629) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 657

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

LCM(1, 657) = 657

GCD(1, 657) = ( 1 x 657 ) / 657

GCD(1, 657) = 657 / 657

GCD(1, 657) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 604

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

LCM(1, 604) = 604

GCD(1, 604) = ( 1 x 604 ) / 604

GCD(1, 604) = 604 / 604

GCD(1, 604) = 1

GCD of 30, 629, 657, 604 is 1
