**Write a Modular C Programming code to solve an IT quiz, What is the biggest possible team size with the exactly the same number of students**

Class A and Class B have 18 and 27 students. Choose teams from each class to play the IT quiz, winning team in both the classes will play in the final match. What is the biggest possible team size with exactly the same number of students?

**Input Format**

two integer numbers separated by space.

**Output Format**

Biggest possible team size with exactly the same number of students.

**Sample Input 0**

```
18 27
```

**Sample Output 0**

```
Biggest possible team = 9
```

**Sample Input 1**

```
204 255
```

**Sample Output 1**

```
Biggest possible team = 51
```

**Sample Input 2**

```
148 355
```

**Sample Output 2**

```
Biggest possible team = 1
```

**Sample Input 3**

```
0 1
```

**Sample Output 3**

```
Invalid value
```

**Sample Input 4**

```
1 0
```

**Sample Output 4**

```
Invalid value
```

**Sample Input 5**

```
0 0
```

**Sample Output 5**

`Invalid value`

**CODE:**

#include<stdio.h> #include<stdlib.h> #include<string.h> #include<math.h> int gcd(int a, int b); int main() { int a,b,p; scanf("%d%d",&a,&b); if(a<=0 || b<=0) { printf("Invalid value"); } else { p=gcd(a,b); printf("Biggest possible team = %d",p); } } int gcd(int a, int b) { int r; while(a) { r=b%a; b=a; a=r; } return b; }

**OUTPUT**
