# Greater Common Divisor

In this lab, you will be implementing a program in C to find the Greatest Common Divisor (GCD) of two positive integers. The GCD of two numbers is the largest positive integer that divides both numbers without leaving a remainder.

To complete this lab, you will need to write a C program that accepts two positive integers as input using `scanf()`

. Your program should then calculate the GCD of these two numbers and print the result using `printf()`

.

Here are a couple of examples of how your program should behave:

Example 1:

`45 15 15`

In this example, the user inputs the numbers 45 and 15. The program calculates the GCD of these two numbers, which is 15, and prints it out.

Example 2:

`18 45 9`

In this example, the user inputs the numbers 18 and 45. The program calculates the GCD of these two numbers, which is 9, and prints it out.

Remember, your program should only print out the GCD without any extra text. There should be no additional `printf()`

statements before accepting the input.

Good luck with your implementation!
