So the Greatest Common Divisior 630, 210, 390, 577 is 1.

Therefore, GCD of numbers 630, 210, 390, 577 is 1

Given Input Data is 630, 210, 390, 577

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

Prime Factorization of 630 is 2 x 3 x 3 x 5 x 7

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

Prime Factorization of 390 is 2 x 3 x 5 x 13

Prime Factorization of 577 is 577

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(630, 210) = 630

GCD(630, 210) = ( 630 x 210 ) / 630

GCD(630, 210) = 132300 / 630

GCD(630, 210) = 210

Step2:

Here we consider the GCD from the above i.e. 210 as first number and the next as 390

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

LCM(210, 390) = 2730

GCD(210, 390) = ( 210 x 390 ) / 2730

GCD(210, 390) = 81900 / 2730

GCD(210, 390) = 30

Step3:

Here we consider the GCD from the above i.e. 30 as first number and the next as 577

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

LCM(30, 577) = 17310

GCD(30, 577) = ( 30 x 577 ) / 17310

GCD(30, 577) = 17310 / 17310

GCD(30, 577) = 1

GCD of 630, 210, 390, 577 is 1
