1, 2, 4, 7, 8, 14, 28, 56

Greatest Common Divisior

We found the divisors of 24, 15, 56 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 24, 15, 56 is 1.

Therefore, GCD of numbers 24, 15, 56 is 1

Given Input Data is 24, 15, 56

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

Prime Factorization of 24 is 2 x 2 x 2 x 3

Prime Factorization of 15 is 3 x 5

Prime Factorization of 56 is 2 x 2 x 2 x 7

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(24, 15) = 120

GCD(24, 15) = ( 24 x 15 ) / 120

GCD(24, 15) = 360 / 120

GCD(24, 15) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 56

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

LCM(3, 56) = 168

GCD(3, 56) = ( 3 x 56 ) / 168

GCD(3, 56) = 168 / 168

GCD(3, 56) = 1

GCD of 24, 15, 56 is 1
