Greatest Common Divisior

We found the divisors of 51, 9, 83, 56 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 51, 9, 83, 56 is 1.

Therefore, GCD of numbers 51, 9, 83, 56 is 1

Given Input Data is 51, 9, 83, 56

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

Prime Factorization of 51 is 3 x 17

Prime Factorization of 9 is 3 x 3

Prime Factorization of 83 is 83

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(51, 9) = 153

GCD(51, 9) = ( 51 x 9 ) / 153

GCD(51, 9) = 459 / 153

GCD(51, 9) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 83

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

LCM(3, 83) = 249

GCD(3, 83) = ( 3 x 83 ) / 249

GCD(3, 83) = 249 / 249

GCD(3, 83) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 56

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

LCM(1, 56) = 56

GCD(1, 56) = ( 1 x 56 ) / 56

GCD(1, 56) = 56 / 56

GCD(1, 56) = 1

GCD of 51, 9, 83, 56 is 1
