Greatest Common Divisior

We found the divisors of 36, 5, 15, 72 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 36, 5, 15, 72 is 1.

Therefore, GCD of numbers 36, 5, 15, 72 is 1

Given Input Data is 36, 5, 15, 72

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

Prime Factorization of 36 is 2 x 2 x 3 x 3

Prime Factorization of 5 is 5

Prime Factorization of 15 is 3 x 5

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(36, 5) = 180

GCD(36, 5) = ( 36 x 5 ) / 180

GCD(36, 5) = 180 / 180

GCD(36, 5) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 15

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

LCM(1, 15) = 15

GCD(1, 15) = ( 1 x 15 ) / 15

GCD(1, 15) = 15 / 15

GCD(1, 15) = 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 36, 5, 15, 72 is 1
