Finding GCD of 661, 338, 27 using Prime Factorization

Given Input Data is 661, 338, 27

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

Prime Factorization of 661 is 661

Prime Factorization of 338 is 2 x 13 x 13

Prime Factorization of 27 is 3 x 3 x 3

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

Finding GCD of 661, 338, 27 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(661, 338) = 223418

GCD(661, 338) = ( 661 x 338 ) / 223418

GCD(661, 338) = 223418 / 223418

GCD(661, 338) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 27

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

LCM(1, 27) = 27

GCD(1, 27) = ( 1 x 27 ) / 27

GCD(1, 27) = 27 / 27

GCD(1, 27) = 1

GCD of 661, 338, 27 is 1
