Finding GCD of 813, 120, 197 using Prime Factorization

Given Input Data is 813, 120, 197

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

Prime Factorization of 813 is 3 x 271

Prime Factorization of 120 is 2 x 2 x 2 x 3 x 5

Prime Factorization of 197 is 197

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

Finding GCD of 813, 120, 197 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(813, 120) = 32520

GCD(813, 120) = ( 813 x 120 ) / 32520

GCD(813, 120) = 97560 / 32520

GCD(813, 120) = 3


Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 197

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

LCM(3, 197) = 591

GCD(3, 197) = ( 3 x 197 ) / 591

GCD(3, 197) = 591 / 591

GCD(3, 197) = 1

GCD of 813, 120, 197 is 1
