Finding GCD of 403, 799, 18 using Prime Factorization

Given Input Data is 403, 799, 18

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

Prime Factorization of 403 is 13 x 31

Prime Factorization of 799 is 17 x 47

Prime Factorization of 18 is 2 x 3 x 3

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

Finding GCD of 403, 799, 18 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(403, 799) = 321997

GCD(403, 799) = ( 403 x 799 ) / 321997

GCD(403, 799) = 321997 / 321997

GCD(403, 799) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 18

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

LCM(1, 18) = 18

GCD(1, 18) = ( 1 x 18 ) / 18

GCD(1, 18) = 18 / 18

GCD(1, 18) = 1

GCD of 403, 799, 18 is 1
