1, 41

Greatest Common Divisior

We found the divisors of 20, 12, 41 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 20, 12, 41 is 1.

Therefore, GCD of numbers 20, 12, 41 is 1

Given Input Data is 20, 12, 41

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

Prime Factorization of 20 is 2 x 2 x 5

Prime Factorization of 12 is 2 x 2 x 3

Prime Factorization of 41 is 41

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(20, 12) = 60

GCD(20, 12) = ( 20 x 12 ) / 60

GCD(20, 12) = 240 / 60

GCD(20, 12) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 41

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

LCM(4, 41) = 164

GCD(4, 41) = ( 4 x 41 ) / 164

GCD(4, 41) = 164 / 164

GCD(4, 41) = 1

GCD of 20, 12, 41 is 1
