Finding GCD of 638, 329, 38 using Prime Factorization

Given Input Data is 638, 329, 38

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

Prime Factorization of 638 is 2 x 11 x 29

Prime Factorization of 329 is 7 x 47

Prime Factorization of 38 is 2 x 19

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

Finding GCD of 638, 329, 38 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(638, 329) = 209902

GCD(638, 329) = ( 638 x 329 ) / 209902

GCD(638, 329) = 209902 / 209902

GCD(638, 329) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 38

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

LCM(1, 38) = 38

GCD(1, 38) = ( 1 x 38 ) / 38

GCD(1, 38) = 38 / 38

GCD(1, 38) = 1

GCD of 638, 329, 38 is 1
