When it comes to combination locks, understanding what the highest number on the lock is can be quite important. Knowing the highest number can help you figure out how many combinations of three number codes can occur.

## What Is The Highest Number On a Combination Lock?

The highest number on a combination lock is typically 39, which is the last number on the lock. The range of possible numbers is 0-39, which allows 40 different possible choices each turn of the dial. That means that the highest number on a combination lock is 39.

So, how many combinations of three number codes can occur with a standard combination lock? Well, the answer is quite a lot! Each combination requires exactly three numbers (i.e. three turns of the dial). For example, the combination 35-40-5 is one of the possible combinations.

To calculate the total number of possible combinations, you must use the formula n^r, where n is the number of choices for each turn of the dial and r is the number of turns of the dial. In this case, n is 40 (the range of possible numbers is 0-39) and r is 3 (since each combination requires exactly three numbers). This means that the total number of possible combinations is 40x40x40, or 64,000.

It’s important to note that not all of these combinations will work on a particular lock. Depending on the manufacturer, some combinations may not be allowed. Also, some locks are made with fewer numbers (e.g. 0-30) which would reduce the number of possible combinations.

In conclusion, the highest number on a combination lock is typically 39, and the total number of possible combinations is 64,000. It is important to remember that not all of these combinations will work on a particular lock, and some locks are made with fewer numbers which would reduce the number of possible combinations.
