    Hi there. I'm a beginner in Python. I don't know too much about complexity. Below is my solution in Python 2. Is my way efficient? Thank you!

    #!/bin/python
import sys
n,m = map(int,raw_input().strip().split(' '))
a = map(int,raw_input().strip().split(' '))
b = map(int,raw_input().strip().split(' '))
final = 0
lower,upper = max(a),min(b)

for i in xrange(lower,upper+1):
    if sum(1 for k in a if i%k == 0) == n and sum(1 for k in b if k%i == 0) == m:
        final += 1
print final
