You are an expert competitive programmer. You will be given a problem statement, test case constraints and example test inputs and outputs. Please reason step by step about the solution (that must respect memory and time limits), then provide a complete implementation in python3.

Your solution must read input from standard input (cin), write output to standard output (cout).
Do not include any debug prints or additional output.

Put your final solution within a single code block:

# Problem
On the trip to campus during the mid semester exam period, Chaneka thinks of two positive integers $$$X$$$ and $$$Y$$$. Since the two integers can be very big, both are represented using their prime factorisations, such that:

- $$$X=A_1^{B_1}\times A_2^{B_2}\times\ldots\times A_N^{B_N}$$$ (each $$$A_i$$$ is prime, each $$$B_i$$$ is positive, and $$$A_1<A_2<\ldots<A_N$$$)
- $$$Y=C_1^{D_1}\times C_2^{D_2}\times\ldots\times C_M^{D_M}$$$ (each $$$C_j$$$ is prime, each $$$D_j$$$ is positive, and $$$C_1<C_2<\ldots<C_M$$$)

Chaneka ponders about these two integers for too long throughout the trip, so Chaneka's friend commands her "Gece, deh!" (move fast) in order to not be late for the exam.

Because of that command, Chaneka comes up with a problem, how many pairs of positive integers $$$p$$$ and $$$q$$$ such that $$$\text{LCM}(p, q) = X$$$ and $$$\text{GCD}(p, q) = Y$$$. Since the answer can be very big, output the answer modulo $$$998\,244\,353$$$.

Notes:

- $$$\text{LCM}(p, q)$$$ is the smallest positive integer that is simultaneously divisible by $$$p$$$ and $$$q$$$.
- $$$\text{GCD}(p, q)$$$ is the biggest positive integer that simultaneously divides $$$p$$$ and $$$q$$$.

## Input Format
The first line contains a single integer $$$N$$$ ($$$1 \leq N \leq 10^5$$$) — the number of distinct primes in the prime factorisation of $$$X$$$.

The second line contains $$$N$$$ integers $$$A_1, A_2, A_3, \ldots, A_N$$$ ($$$2 \leq A_1 < A_2 < \ldots < A_N \leq 2 \cdot 10^6$$$; each $$$A_i$$$ is prime) — the primes in the prime factorisation of $$$X$$$.

The third line contains $$$N$$$ integers $$$B_1, B_2, B_3, \ldots, B_N$$$ ($$$1 \leq B_i \leq 10^5$$$) — the exponents in the prime factorisation of $$$X$$$.

The fourth line contains a single integer $$$M$$$ ($$$1 \leq M \leq 10^5$$$) — the number of distinct primes in the prime factorisation of $$$Y$$$.

The fifth line contains $$$M$$$ integers $$$C_1, C_2, C_3, \ldots, C_M$$$ ($$$2 \leq C_1 < C_2 < \ldots < C_M \leq 2 \cdot 10^6$$$; each $$$C_j$$$ is prime) — the primes in the prime factorisation of $$$Y$$$.

The sixth line contains $$$M$$$ integers $$$D_1, D_2, D_3, \ldots, D_M$$$ ($$$1 \leq D_j \leq 10^5$$$) — the exponents in the prime factorisation of $$$Y$$$.

## Output Format
An integer representing the number of pairs of positive integers $$$p$$$ and $$$q$$$ such that $$$\text{LCM}(p, q) = X$$$ and $$$\text{GCD}(p, q) = Y$$$, modulo $$$998\,244\,353$$$.

## Note
In the first example, the integers are as follows:

- $$$X=2^2\times3^1\times5^1\times7^2=2940$$$
- $$$Y=3^1\times7^1=21$$$

The following are all possible pairs of $$$p$$$ and $$$q$$$:

- $$$p=21$$$, $$$q=2940$$$
- $$$p=84$$$, $$$q=735$$$
- $$$p=105$$$, $$$q=588$$$
- $$$p=147$$$, $$$q=420$$$
- $$$p=420$$$, $$$q=147$$$
- $$$p=588$$$, $$$q=105$$$
- $$$p=735$$$, $$$q=84$$$
- $$$p=2940$$$, $$$q=21$$$

In the third example, the integers are as follows:

- $$$X=2^1\times5^1=10$$$
- $$$Y=2^1\times3^1=6$$$

There is no pair $$$p$$$ and $$$q$$$ that simultaneously satisfies $$$\text{LCM}(p,q)=10$$$ and $$$\text{GCD}(p,q)=6$$$.

Now solve the problem and return the code.
