# Between Two Sets

# Between Two Sets

There will be two arrays of integers. Determine all integers that satisfy the following two conditions:

- The elements of the first array are all factors of the integer being considered
- The integer being considered is a factor of all elements of the second array

These numbers are referred to as being *between* the two arrays. Determine how many such numbers exist.

**Example**

There are two numbers between the arrays: and .

, , and for the first value.

, and , for the second value.
Return .

**Function Description**

Complete the *getTotalX* function in the editor below. It should return the number of integers that are betwen the sets.

getTotalX has the following parameter(s):

*int a[n]*: an array of integers*int b[m]*: an array of integers

**Returns**

*int:*the number of integers that are between the sets

**Input Format**

The first line contains two space-separated integers, and , the number of elements in arrays and .

The second line contains distinct space-separated integers where .

The third line contains distinct space-separated integers where .

**Constraints**

**Sample Input**

```
2 3
2 4
16 32 96
```

**Sample Output**

```
3
```

**Explanation**

2 and 4 divide evenly into 4, 8, 12 and 16.

4, 8 and 16 divide evenly into 16, 32, 96.

4, 8 and 16 are the only three numbers for which each element of a is a factor and each is a factor of all elements of b.
