Greatest Common Divisior

We found the divisors of 69, 33, 68, 29 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 69, 33, 68, 29 is 1.

Therefore, GCD of numbers 69, 33, 68, 29 is 1

Given Input Data is 69, 33, 68, 29

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

Prime Factorization of 69 is 3 x 23

Prime Factorization of 33 is 3 x 11

Prime Factorization of 68 is 2 x 2 x 17

Prime Factorization of 29 is 29

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(69, 33) = 759

GCD(69, 33) = ( 69 x 33 ) / 759

GCD(69, 33) = 2277 / 759

GCD(69, 33) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 68

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

LCM(3, 68) = 204

GCD(3, 68) = ( 3 x 68 ) / 204

GCD(3, 68) = 204 / 204

GCD(3, 68) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 29

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

LCM(1, 29) = 29

GCD(1, 29) = ( 1 x 29 ) / 29

GCD(1, 29) = 29 / 29

GCD(1, 29) = 1

GCD of 69, 33, 68, 29 is 1
