Given Input Data is 261, 447, 533

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

Prime Factorization of 261 is 3 x 3 x 29

Prime Factorization of 447 is 3 x 149

Prime Factorization of 533 is 13 x 41

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(261, 447) = 38889

GCD(261, 447) = ( 261 x 447 ) / 38889

GCD(261, 447) = 116667 / 38889

GCD(261, 447) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 533

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

LCM(3, 533) = 1599

GCD(3, 533) = ( 3 x 533 ) / 1599

GCD(3, 533) = 1599 / 1599

GCD(3, 533) = 1

GCD of 261, 447, 533 is 1
