Therefore, GCD of numbers 45, 681, 815, 339 is 1

Given Input Data is 45, 681, 815, 339

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

Prime Factorization of 45 is 3 x 3 x 5

Prime Factorization of 681 is 3 x 227

Prime Factorization of 815 is 5 x 163

Prime Factorization of 339 is 3 x 113

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(45, 681) = 10215

GCD(45, 681) = ( 45 x 681 ) / 10215

GCD(45, 681) = 30645 / 10215

GCD(45, 681) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 815

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

LCM(3, 815) = 2445

GCD(3, 815) = ( 3 x 815 ) / 2445

GCD(3, 815) = 2445 / 2445

GCD(3, 815) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 339

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

LCM(1, 339) = 339

GCD(1, 339) = ( 1 x 339 ) / 339

GCD(1, 339) = 339 / 339

GCD(1, 339) = 1

GCD of 45, 681, 815, 339 is 1
