How do I find the factor combinations of the number 164,423?

Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 164,423, it is easier to work with a table - it's called factoring from the outside in.

Outside in Factoring

We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.

1 164,423
-1 -164,423

Why are the negative numbers included?

When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 164,423.

Example:
1 x 164,423 = 164,423
and
-1 x -164,423 = 164,423
Notice both answers equal 164,423

With that explanation out of the way, let's continue. Next, we take the number 164,423 and divide it by 2:

164,423 ÷ 2 = 82,211.5

If the quotient is a whole number, then 2 and 82,211.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.

Here is what our table should look like at this step:

1 164,423
-1 -164,423

Now, we try dividing 164,423 by 3:

164,423 ÷ 3 = 54,807.6667

If the quotient is a whole number, then 3 and 54,807.6667 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.

Here is what our table should look like at this step:

1 164,423
-1 -164,423

Let's try dividing by 4:

164,423 ÷ 4 = 41,105.75

If the quotient is a whole number, then 4 and 41,105.75 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.

Here is what our table should look like at this step:

1 164,423
-1 164,423
Keep dividing by the next highest number until you cannot divide anymore.

If you did it right, you will end up with this table:

17832835811,98123,489164,423
-1-7-83-283-581-1,981-23,489-164,423
