Finding GCD of 247, 187, 209 using Prime Factorization

Given Input Data is 247, 187, 209

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

Prime Factorization of 247 is 13 x 19

Prime Factorization of 187 is 11 x 17

Prime Factorization of 209 is 11 x 19

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

Finding GCD of 247, 187, 209 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(247, 187) = 46189

GCD(247, 187) = ( 247 x 187 ) / 46189

GCD(247, 187) = 46189 / 46189

GCD(247, 187) = 1


Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 209

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

LCM(1, 209) = 209

GCD(1, 209) = ( 1 x 209 ) / 209

GCD(1, 209) = 209 / 209

GCD(1, 209) = 1

GCD of 247, 187, 209 is 1
