Greatest Common Divisior

We found the divisors of 10, 2, 27, 72 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 10, 2, 27, 72 is 1.

Therefore, GCD of numbers 10, 2, 27, 72 is 1

Given Input Data is 10, 2, 27, 72

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

Prime Factorization of 10 is 2 x 5

Prime Factorization of 2 is 2

Prime Factorization of 27 is 3 x 3 x 3

Prime Factorization of 72 is 2 x 2 x 2 x 3 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(10, 2) = 10

GCD(10, 2) = ( 10 x 2 ) / 10

GCD(10, 2) = 20 / 10

GCD(10, 2) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 27

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

LCM(2, 27) = 54

GCD(2, 27) = ( 2 x 27 ) / 54

GCD(2, 27) = 54 / 54

GCD(2, 27) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 72

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

LCM(1, 72) = 72

GCD(1, 72) = ( 1 x 72 ) / 72

GCD(1, 72) = 72 / 72

GCD(1, 72) = 1

GCD of 10, 2, 27, 72 is 1
