Finding GCD of 387, 729, 808 using Prime Factorization

Given Input Data is 387, 729, 808

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

Prime Factorization of 387 is 3 x 3 x 43

Prime Factorization of 729 is 3 x 3 x 3 x 3 x 3 x 3

Prime Factorization of 808 is 2 x 2 x 2 x 101

Finding GCD of 387, 729, 808 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(387, 729) = 31347

GCD(387, 729) = ( 387 x 729 ) / 31347

GCD(387, 729) = 282123 / 31347

GCD(387, 729) = 9

Step2:

Here we consider the GCD from the above i.e. 9 as first number and the next as 808

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

LCM(9, 808) = 7272

GCD(9, 808) = ( 9 x 808 ) / 7272

GCD(9, 808) = 7272 / 7272

GCD(9, 808) = 1

GCD of 387, 729, 808 is 1
