Greatest Common Divisior

We found the divisors of 630, 141, 672, 730 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 630, 141, 672, 730 is 1.

Therefore, GCD of numbers 630, 141, 672, 730 is 1

Given Input Data is 630, 141, 672, 730

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 141 is 3 x 47

Prime Factorization of 672 is 2 x 2 x 2 x 2 x 2 x 3 x 7

Prime Factorization of 730 is 2 x 5 x 73

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, 141) = 29610

GCD(630, 141) = ( 630 x 141 ) / 29610

GCD(630, 141) = 88830 / 29610

GCD(630, 141) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 672

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

LCM(3, 672) = 672

GCD(3, 672) = ( 3 x 672 ) / 672

GCD(3, 672) = 2016 / 672

GCD(3, 672) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 730

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

LCM(3, 730) = 2190

GCD(3, 730) = ( 3 x 730 ) / 2190

GCD(3, 730) = 2190 / 2190

GCD(3, 730) = 1

GCD of 630, 141, 672, 730 is 1
