Greatest Common Divisior

We found the divisors of 10, 20, 69, 41 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 10, 20, 69, 41 is 1.

Therefore, GCD of numbers 10, 20, 69, 41 is 1

Given Input Data is 10, 20, 69, 41

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

Prime Factorization of 10 is 2 x 5

Prime Factorization of 20 is 2 x 2 x 5

Prime Factorization of 69 is 3 x 23

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(10, 20) = 20

GCD(10, 20) = ( 10 x 20 ) / 20

GCD(10, 20) = 200 / 20

GCD(10, 20) = 10

Step2:

Here we consider the GCD from the above i.e. 10 as first number and the next as 69

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

LCM(10, 69) = 690

GCD(10, 69) = ( 10 x 69 ) / 690

GCD(10, 69) = 690 / 690

GCD(10, 69) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 41

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

LCM(1, 41) = 41

GCD(1, 41) = ( 1 x 41 ) / 41

GCD(1, 41) = 41 / 41

GCD(1, 41) = 1

GCD of 10, 20, 69, 41 is 1
