Therefore, GCD of numbers 447, 753, 530, 809 is 1

Given Input Data is 447, 753, 530, 809

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

Prime Factorization of 447 is 3 x 149

Prime Factorization of 753 is 3 x 251

Prime Factorization of 530 is 2 x 5 x 53

Prime Factorization of 809 is 809

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, 753) = 112197

GCD(447, 753) = ( 447 x 753 ) / 112197

GCD(447, 753) = 336591 / 112197

GCD(447, 753) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 530

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

LCM(3, 530) = 1590

GCD(3, 530) = ( 3 x 530 ) / 1590

GCD(3, 530) = 1590 / 1590

GCD(3, 530) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 809

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

LCM(1, 809) = 809

GCD(1, 809) = ( 1 x 809 ) / 809

GCD(1, 809) = 809 / 809

GCD(1, 809) = 1

GCD of 447, 753, 530, 809 is 1
