Greatest Common Divisior

We found the divisors of 30, 427, 873, 663 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 30, 427, 873, 663 is 1.

Therefore, GCD of numbers 30, 427, 873, 663 is 1

Given Input Data is 30, 427, 873, 663

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 427 is 7 x 61

Prime Factorization of 873 is 3 x 3 x 97

Prime Factorization of 663 is 3 x 13 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(30, 427) = 12810

GCD(30, 427) = ( 30 x 427 ) / 12810

GCD(30, 427) = 12810 / 12810

GCD(30, 427) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 873

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

LCM(1, 873) = 873

GCD(1, 873) = ( 1 x 873 ) / 873

GCD(1, 873) = 873 / 873

GCD(1, 873) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 663

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

LCM(1, 663) = 663

GCD(1, 663) = ( 1 x 663 ) / 663

GCD(1, 663) = 663 / 663

GCD(1, 663) = 1

GCD of 30, 427, 873, 663 is 1
