We found the divisors of 23, 73, 39, 56 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 23, 73, 39, 56 is 1.

Therefore, GCD of numbers 23, 73, 39, 56 is 1

Given Input Data is 23, 73, 39, 56

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

Prime Factorization of 23 is 23

Prime Factorization of 73 is 73

Prime Factorization of 39 is 3 x 13

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(23, 73) = 1679

GCD(23, 73) = ( 23 x 73 ) / 1679

GCD(23, 73) = 1679 / 1679

GCD(23, 73) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 39

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

LCM(1, 39) = 39

GCD(1, 39) = ( 1 x 39 ) / 39

GCD(1, 39) = 39 / 39

GCD(1, 39) = 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 23, 73, 39, 56 is 1
