We found the divisors of 447, 440, 53, 457 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 447, 440, 53, 457 is 1.

Therefore, GCD of numbers 447, 440, 53, 457 is 1

Given Input Data is 447, 440, 53, 457

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

Prime Factorization of 447 is 3 x 149

Prime Factorization of 440 is 2 x 2 x 2 x 5 x 11

Prime Factorization of 53 is 53

Prime Factorization of 457 is 457

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, 440) = 196680

GCD(447, 440) = ( 447 x 440 ) / 196680

GCD(447, 440) = 196680 / 196680

GCD(447, 440) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 53

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

LCM(1, 53) = 53

GCD(1, 53) = ( 1 x 53 ) / 53

GCD(1, 53) = 53 / 53

GCD(1, 53) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 457

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

LCM(1, 457) = 457

GCD(1, 457) = ( 1 x 457 ) / 457

GCD(1, 457) = 457 / 457

GCD(1, 457) = 1

GCD of 447, 440, 53, 457 is 1
