Greatest Common Divisior

We found the divisors of 18, 14, 65 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 18, 14, 65 is 1.

Therefore, GCD of numbers 18, 14, 65 is 1

Given Input Data is 18, 14, 65

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

Prime Factorization of 18 is 2 x 3 x 3

Prime Factorization of 14 is 2 x 7

Prime Factorization of 65 is 5 x 13

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

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(18, 14) = 126

GCD(18, 14) = ( 18 x 14 ) / 126

GCD(18, 14) = 252 / 126

GCD(18, 14) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 65

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

LCM(2, 65) = 130

GCD(2, 65) = ( 2 x 65 ) / 130

GCD(2, 65) = 130 / 130

GCD(2, 65) = 1

GCD of 18, 14, 65 is 1
