Problem E
Dual Divisibility
Given two positive integers $a$ and $b$ with the same number of digits, compute the number of divisors of $a$ that have $b$ as a divisor.
Input
The first and only line contains the integers $a$ and $b$ ($1 \le b \le a \le 10^{18}$).
Output
Output the number of divisors of $a$ that have $b$ as a divisor.
Explanation of sample 1
In the first example, the four divisors are $12$, $24$, $48$, $96$.
| Sample Input 1 | Sample Output 1 |
