151_A. Soft Drinking
This winter is so cold in Nvodsk! A group of n friends decided to buy k bottles of a soft drink called "Take-It-Light" to warm up a bit. Each bottle has l milliliters of the drink. Also they bought c limes and cut each of them into d slices. After that they found p grams of salt.

To make a toast, each friend needs nl milliliters of the drink, a slice of lime and np grams of salt. The friends want to make as many toasts as they can, provided they all drink the same amount. How many toasts can each friend make?

Input

The first and only line contains positive integers n, k, l, c, d, p, nl, np, not exceeding 1000 and no less than 1. The numbers are separated by exactly one space.

Output

Print a single integer — the number of toasts each friend can make.

Note

A comment to the first sample: 

Overall the friends have 4 * 5 = 20 milliliters of the drink, it is enough to make 20 / 3 = 6 toasts. The limes are enough for 10 * 8 = 80 toasts and the salt is enough for 100 / 1 = 100 toasts. However, there are 3 friends in the group, so the answer is min(6, 80, 100) / 3 = 2.
```python
party = list(map(int, input().split()))
friends, bottles, ml, limes, lime_slices, salt, friend_ml, friend_salt = party


total_gas = bottles * ml
total_limes = limes * lime_slices

rotation_ml = friend_ml * friends


q_tosts = -1
while all(x >= 0 for x in (salt, total_gas, total_limes)):
    total_gas -= rotation_ml 
    total_limes -= friends
    salt -= friend_salt * friends
    q_tosts += 1
print(q_tosts)
```
