# Find the sum of multiples of X between A and B

Find the sum of multiples of X between A and B

Given the values for X, A and B, the program must print the sum of multiples of X from A to B (inclusive of A and B).

The first line contains the value of X.

The second line contains the value of A.

The third line contains the value of B.

The first line contains the sum of multiples of X from A to B (inclusive of A and B).

1 <= X <= 100

1 <= A <= 100000

A <= B <= 1000000

Input:

5

10

25

Output:

70

Explanation:

The multiples of 5 from 10 to 25 are, 10,15,20,25 and their sum is 70

**Input Format:**The first line contains the value of X.

The second line contains the value of A.

The third line contains the value of B.

**Output Format:**The first line contains the sum of multiples of X from A to B (inclusive of A and B).

**Boundary Conditions:**1 <= X <= 100

1 <= A <= 100000

A <= B <= 1000000

**Example Input/Output 1:**Input:

5

10

25

Output:

70

Explanation:

The multiples of 5 from 10 to 25 are, 10,15,20,25 and their sum is 70

**Code:**

#include <iostream>

using namespace std;

int main(int argc, char** argv)

{

int n,a,b,i,sum=0;

cin>>n>>a>>b;

for(i=a;i<=b;i++)

{

if(i%n==0)

sum+=i;

}

cout<<sum;

}
