Therefore, GCD of numbers 441, 189, 275, 447 is 1

Given Input Data is 441, 189, 275, 447

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

Prime Factorization of 441 is 3 x 3 x 7 x 7

Prime Factorization of 189 is 3 x 3 x 3 x 7

Prime Factorization of 275 is 5 x 5 x 11

Prime Factorization of 447 is 3 x 149

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(441, 189) = 1323

GCD(441, 189) = ( 441 x 189 ) / 1323

GCD(441, 189) = 83349 / 1323

GCD(441, 189) = 63

Step2:

Here we consider the GCD from the above i.e. 63 as first number and the next as 275

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

LCM(63, 275) = 17325

GCD(63, 275) = ( 63 x 275 ) / 17325

GCD(63, 275) = 17325 / 17325

GCD(63, 275) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 447

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

LCM(1, 447) = 447

GCD(1, 447) = ( 1 x 447 ) / 447

GCD(1, 447) = 447 / 447

GCD(1, 447) = 1

GCD of 441, 189, 275, 447 is 1
