# C program to check given number is divisible by A and B

In this C program, we will read an integer number and check whether given integer number is divisible by A and B. Here, A and B are the divisors given by the user.

Given an integer number number and two divisors A and B, we have to check whether number is divisible by A and B in C.

Example:

```    Input:
number = 100
A = 10, B = 20
Output:
100 is divisible by 10 and 20

Input:
number = 90
A = 10, B = 20
Output:
90 is not divisible by 10 and 20
```

To check whether a given number is divisible by two divisors (A and B) or not, we are creating a function named CheckDivision() which will return 1, if number is divisible by both divisors else it will return 0.

Function declaration:

` int CheckDivision(int num, int a , int b)`

Here,

• int is the return type
• CheckDivision is the function name
• int num is the number to divide
• int a , int b are the divisors

Statements with function calling:

```    if(CheckDivision(number,A,B))
printf("%d is divisible by %d and %d\n",number,A,B);
else
printf("%d is not divisible by %d and %d\n",number,A,B);
```

Statement printf("%d is divisible by %d and %d\n",number,A,B); will be executed if function will return 1 else printf("%d is not divisible by %d and %d\n",number,A,B); will be executed.

## Program to check number is divisible by A and B in C

```/**
C program to check given number
is divisible by A and B
Here, A and B are integers
*/

#include <stdio.h>

//function will return 1 if given number is
//divisible by both numbers a and b
int CheckDivision(int num, int a , int b)
{
//we have to check whether num is
//divisible by a and b
if( num%a==0 && num%b==0 )
return 1;
else
return 0;
}

// main function
int main()
{
int number=0,A=0,B=0;

printf("Enter any integer number : ");
scanf("%d",&number);

printf("Enter first divisor : ");
scanf("%d",&A);

printf("Enter second divisor : ");
scanf("%d",&B);

if(CheckDivision(number,A,B))
printf("%d is divisible by %d and %d\n",number,A,B);
else
printf("%d is not divisible by %d and %d\n",number,A,B);

return 0;
}
```

Output

```Run 1 :
Enter any integer number : 100
Enter first divisor : 10
Enter second divisor : 20
100 is divisible by 10 and 20

Run 2:
Enter any integer number : 90
Enter first divisor : 10
Enter second divisor : 20
90 is not divisible by 10 and 20
```
