1, 2, 4, 5, 8, 10, 16, 20, 40, 80

Greatest Common Divisior

We found the divisors of 12, 33, 80 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 12, 33, 80 is 1.

Therefore, GCD of numbers 12, 33, 80 is 1

Given Input Data is 12, 33, 80

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

Prime Factorization of 12 is 2 x 2 x 3

Prime Factorization of 33 is 3 x 11

Prime Factorization of 80 is 2 x 2 x 2 x 2 x 5

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(12, 33) = 132

GCD(12, 33) = ( 12 x 33 ) / 132

GCD(12, 33) = 396 / 132

GCD(12, 33) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 80

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

LCM(3, 80) = 240

GCD(3, 80) = ( 3 x 80 ) / 240

GCD(3, 80) = 240 / 240

GCD(3, 80) = 1

GCD of 12, 33, 80 is 1
