Given Input Data is 455, 533, 743

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

Prime Factorization of 455 is 5 x 7 x 13

Prime Factorization of 533 is 13 x 41

Prime Factorization of 743 is 743

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(455, 533) = 18655

GCD(455, 533) = ( 455 x 533 ) / 18655

GCD(455, 533) = 242515 / 18655

GCD(455, 533) = 13

Step2:

Here we consider the GCD from the above i.e. 13 as first number and the next as 743

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

LCM(13, 743) = 9659

GCD(13, 743) = ( 13 x 743 ) / 9659

GCD(13, 743) = 9659 / 9659

GCD(13, 743) = 1

GCD of 455, 533, 743 is 1
