Therefore, GCD of numbers 447, 988, 289 is 1

Given Input Data is 447, 988, 289

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

Prime Factorization of 447 is 3 x 149

Prime Factorization of 988 is 2 x 2 x 13 x 19

Prime Factorization of 289 is 17 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(447, 988) = 441636

GCD(447, 988) = ( 447 x 988 ) / 441636

GCD(447, 988) = 441636 / 441636

GCD(447, 988) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 289

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

LCM(1, 289) = 289

GCD(1, 289) = ( 1 x 289 ) / 289

GCD(1, 289) = 289 / 289

GCD(1, 289) = 1

GCD of 447, 988, 289 is 1
