Finding GCD of 390, 321, 397 using Prime Factorization

Given Input Data is 390, 321, 397

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

Prime Factorization of 390 is 2 x 3 x 5 x 13

Prime Factorization of 321 is 3 x 107

Prime Factorization of 397 is 397

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

Finding GCD of 390, 321, 397 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(390, 321) = 41730

GCD(390, 321) = ( 390 x 321 ) / 41730

GCD(390, 321) = 125190 / 41730

GCD(390, 321) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 397

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

LCM(3, 397) = 1191

GCD(3, 397) = ( 3 x 397 ) / 1191

GCD(3, 397) = 1191 / 1191

GCD(3, 397) = 1

GCD of 390, 321, 397 is 1
