Finding GCD of 209, 219, 257 using Prime Factorization

Given Input Data is 209, 219, 257

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

Prime Factorization of 209 is 11 x 19

Prime Factorization of 219 is 3 x 73

Prime Factorization of 257 is 257

The above numbers do not have any common prime factor. So GCD is 1

Finding GCD of 209, 219, 257 using LCM Formula

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(209, 219) = 45771

GCD(209, 219) = ( 209 x 219 ) / 45771

GCD(209, 219) = 45771 / 45771

GCD(209, 219) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 257

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

LCM(1, 257) = 257

GCD(1, 257) = ( 1 x 257 ) / 257

GCD(1, 257) = 257 / 257

GCD(1, 257) = 1

GCD of 209, 219, 257 is 1
