Greatest Common Divisior

We found the divisors of 34, 38, 18 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 34, 38, 18 is 2.

Therefore, GCD of numbers 34, 38, 18 is 2

Given Input Data is 34, 38, 18

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

Prime Factorization of 34 is 2 x 17

Prime Factorization of 38 is 2 x 19

Prime Factorization of 18 is 2 x 3 x 3

Highest common occurrences in the given inputs are 2¹

Multiplying them we get the GCD as 2

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(34, 38) = 646

GCD(34, 38) = ( 34 x 38 ) / 646

GCD(34, 38) = 1292 / 646

GCD(34, 38) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 18

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

LCM(2, 18) = 18

GCD(2, 18) = ( 2 x 18 ) / 18

GCD(2, 18) = 36 / 18

GCD(2, 18) = 2

GCD of 34, 38, 18 is 2
