Greatest Common Divisior

We found the divisors of 16, 69, 12 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 16, 69, 12 is 1.

Therefore, GCD of numbers 16, 69, 12 is 1

Given Input Data is 16, 69, 12

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

Prime Factorization of 16 is 2 x 2 x 2 x 2

Prime Factorization of 69 is 3 x 23

Prime Factorization of 12 is 2 x 2 x 3

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(16, 69) = 1104

GCD(16, 69) = ( 16 x 69 ) / 1104

GCD(16, 69) = 1104 / 1104

GCD(16, 69) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 12

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

LCM(1, 12) = 12

GCD(1, 12) = ( 1 x 12 ) / 12

GCD(1, 12) = 12 / 12

GCD(1, 12) = 1

GCD of 16, 69, 12 is 1
