All submissions for this problem are available.### Read problems statements in [Mandarin chinese](http://www.codechef.com/download/translated/COOK91/mandarin/CTHREE.pdf), [Russian](http://www.codechef.com/download/translated/COOK91/russian/CTHREE.pdf) and [Vietnamese](http://www.codechef.com/download/translated/COOK91/vietnamese/CTHREE.pdf) as well.
Today, Chef was trying to solve a problem he found pretty hard: Given an integer **N** and a triple of integers (**a**, **b**, **c**), compute the number of triples of positive integers (**x**, **y**, **z**) such that **N** = **x** ยท **y** ยท **z**, **x** โค **a**, **y** โค **b** and **z** โค **c**.
Can you help Chef solve this problem?
Two [triples](https://en.wikipedia.org/wiki/Tuple) (**x1**, **y1**, **z1**) and (**x2**, **y2**, **z2**) differ if **x1** is not equal to **x2** or **y1** is not equal to **y2** or **z1** is not equal to **z2**.
### Input
- The first line of the input contains a single integer **T** denoting the number of test cases. The description of **T** test cases follows.
- The first and only line of each test case contains four space-separated integers **N**, **a**, **b** and **c**.
### Output
For each test case, print a single line containing one integer โ the number of valid triples (**x**, **y**, **z**).
### Constraints
- 1 โค **T** โค 20
- 1 โค **N** โค 109
- 1 โค **a**, **b**, **c** โค 106
### Example

</pre>### Explanation
**Example case 1:** There are 10 valid triples (**x**, **y**, **z**): (1, 10, 10), (1, 20, 5), (2, 5, 10), (2, 10, 5), (4, 5, 5), (5, 2, 10), (5, 4, 5), (5, 5, 4), (5, 10, 2), (5, 20, 1).
