Greatest Common Divisior

We found the divisors of 75, 9, 73, 17 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 75, 9, 73, 17 is 1.

Therefore, GCD of numbers 75, 9, 73, 17 is 1

Given Input Data is 75, 9, 73, 17

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

Prime Factorization of 75 is 3 x 5 x 5

Prime Factorization of 9 is 3 x 3

Prime Factorization of 73 is 73

Prime Factorization of 17 is 17

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(75, 9) = 225

GCD(75, 9) = ( 75 x 9 ) / 225

GCD(75, 9) = 675 / 225

GCD(75, 9) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 73

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

LCM(3, 73) = 219

GCD(3, 73) = ( 3 x 73 ) / 219

GCD(3, 73) = 219 / 219

GCD(3, 73) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 17

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

LCM(1, 17) = 17

GCD(1, 17) = ( 1 x 17 ) / 17

GCD(1, 17) = 17 / 17

GCD(1, 17) = 1

GCD of 75, 9, 73, 17 is 1
