how many possible combinations on a 10 digit lock?
157883
For example, a lock with ten numbers would be 10^4 or 10 000 different four digit combinations. Considering the lock only uses number: 10 x 10 x 10 x 10. 10,000 combinations.

With a four digit PIN, there are a possible 10,000 combinations. But with a six digit code, there are 1 million possible combos, making it a lot tougher for someone to crack your security code. If you are currently using a four digit PIN and update your software, you will need to manually opt in for the six digit PIN.

FACT: most master\lock padlocks have around 64,000 possible combinations. ANOTHER FACT: this instructable ( if done properly) will turn 64,000 into 100. so go to step 1 and let's get started.

With three columns, each with ten possibilities, the number of total combinations is 10 × 10 × 10, or 1000. With three switches, each with two possibilities, the number of total combinations is 2 × 2 × 2, or 8.

Those mathematic possibilities are called key bittings. There are only so many ways you can arrange the pins inside the lock, or the cuts on the key in order to get the maximum number of bittings possible. Most common locks only offer a few thousand bittings in a simple masterkey system.

The number of combinations that are possible with 10 numbers is 1,023.

The 5-button Simplex Lock has only 1,082 possible combinations. By comparison, this 3-dial lock (three wheels, each with digits 0-9) has 10   10   10 = 1, 000 possible combinations.

Explanation: There are 5 choices for the first digit. giving 5×5=25 possible combinations. giving 5×4=20 possible combinations.

The Five-bit Code Using these two states in a group of five-bits to represent each character gives a total of 32 unique combinations. You can create a list of these 32 five-bit combinations by starting with the '00000' combination first and then counting in binary until you reach the combination '11111'.

Assuming no five-digit number can begin with zero, there are 9 possible choices for the first digit. Then there are 10 possible choices for each of the remaining four digits. Therefore, you have 9 x 10 x 10 x 10 x 10 combinations, or 9 x 10^4, which is 90,000 different combinations.

There are, you see, 3 x 2 x 1 = 6 possible ways of arranging the three digits. Therefore in that set of 720 possibilities, each unique combination of three digits is represented 6 times. So we just divide by 6.

The number of 5-digit combinations is 10 5=100,000. So, one more than 99,999. You can generalize that: the number of N-digit combinations is 10 N.

Answer and Explanation: The number of possible 16-digit combinations, where repetition is allowed is 10,000,000,000,000,000.

['Answer: There are 9,999 different combinations in a 4-digit lock.', 'Explanation: The 4-digit number on a lock begins from 0000 and ends up to 9999 which are:', 'From 0000 to 0999 there are 999 combinations. ( ... ', 'From 1,000 to 9,999 there are 8,999 combinations (9,000)', 'And now we have 1,000+9,000=10,000 combinations total.']

The number of 5-digit combinations is 10 5=100,000. So, one more than 99,999. You can generalize that: the number of N-digit combinations is 10 N. Now, this assumes that you count 00000 or 00534 as "5-digit numbers".
