Given Input Data is 57, 209, 215, 443

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

Prime Factorization of 57 is 3 x 19

Prime Factorization of 209 is 11 x 19

Prime Factorization of 215 is 5 x 43

Prime Factorization of 443 is 443

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(57, 209) = 627

GCD(57, 209) = ( 57 x 209 ) / 627

GCD(57, 209) = 11913 / 627

GCD(57, 209) = 19

Step2:

Here we consider the GCD from the above i.e. 19 as first number and the next as 215

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

LCM(19, 215) = 4085

GCD(19, 215) = ( 19 x 215 ) / 4085

GCD(19, 215) = 4085 / 4085

GCD(19, 215) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 443

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

LCM(1, 443) = 443

GCD(1, 443) = ( 1 x 443 ) / 443

GCD(1, 443) = 443 / 443

GCD(1, 443) = 1

GCD of 57, 209, 215, 443 is 1
