Therefore, GCD of numbers 30, 681, 244, 684 is 1

Given Input Data is 30, 681, 244, 684

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 681 is 3 x 227

Prime Factorization of 244 is 2 x 2 x 61

Prime Factorization of 684 is 2 x 2 x 3 x 3 x 19

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, 681) = 6810

GCD(30, 681) = ( 30 x 681 ) / 6810

GCD(30, 681) = 20430 / 6810

GCD(30, 681) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 244

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

LCM(3, 244) = 732

GCD(3, 244) = ( 3 x 244 ) / 732

GCD(3, 244) = 732 / 732

GCD(3, 244) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 684

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

LCM(1, 684) = 684

GCD(1, 684) = ( 1 x 684 ) / 684

GCD(1, 684) = 684 / 684

GCD(1, 684) = 1

GCD of 30, 681, 244, 684 is 1
