## Jumping Bunnies

Bunnies are very cute animals who likes to jump a lot. Every bunny has his own range of jump. Lets say there are bunnies and bunny jumps units. Consider a 1-D plane, where initially bunnies are at . All of them starts jumping in forward direction.

For example, consider the case of bunny. Initially he is at . After first jump, he will be at point . After second, he will be at and so on. After jump, he will be at point .

Two bunnies can only meet each other when they are on the ground. When on the ground, a bunny can wait any amount of time. Being a social animal, all of them decide to meet at the next point where *all* of them will be on the ground. You have to find the nearest point where all the bunnies can meet.

For example, if there are bunnies where , , . Nearest point where all bunnies can meet again is at . First bunny has to jump six times, for second it is times and for third it is times.

Help bunnies to find the nearest point where they can meet again.

**Input Format**

First line will contain an integer, , represeting the number of bunnies. Second line will contain space separated integer, , representing the jumping distance of them.

**Output Format**

Print the nearest location where all bunnies can meet again.

**Constraints**

For each test case it is guaranteed that solution will not exceed .

**Sample Input #00**

```
3
2 3 4
```

**Sample Output #00**

```
12
```

**Sample Input #01**

```
2
1 3
```

**Sample Output #01**

```
3
```

**Explanation**

*Sample Case #00:* This is the same example mentioned in the statement above.

*Sample Case #01:* First bunny has to jump times to point , whereas second bunny has to jump only one time to go at point . Point will serve as their meeting point.
