Therefore, GCD of numbers 399, 456, 601, 681 is 1

Given Input Data is 399, 456, 601, 681

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

Prime Factorization of 399 is 3 x 7 x 19

Prime Factorization of 456 is 2 x 2 x 2 x 3 x 19

Prime Factorization of 601 is 601

Prime Factorization of 681 is 3 x 227

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(399, 456) = 3192

GCD(399, 456) = ( 399 x 456 ) / 3192

GCD(399, 456) = 181944 / 3192

GCD(399, 456) = 57

Step2:

Here we consider the GCD from the above i.e. 57 as first number and the next as 601

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

LCM(57, 601) = 34257

GCD(57, 601) = ( 57 x 601 ) / 34257

GCD(57, 601) = 34257 / 34257

GCD(57, 601) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 681

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

LCM(1, 681) = 681

GCD(1, 681) = ( 1 x 681 ) / 681

GCD(1, 681) = 681 / 681

GCD(1, 681) = 1

GCD of 399, 456, 601, 681 is 1
