How do I find the factor combinations of the number 161,928?

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 161,928, 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.

1 161,928
-1 -161,928

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 161,928.

Example:
1 x 161,928 = 161,928
and
-1 x -161,928 = 161,928
Notice both answers equal 161,928

With that explanation out of the way, let's continue. Next, we take the number 161,928 and divide it by 2:

161,928 ÷ 2 = 80,964

If the quotient is a whole number, then 2 and 80,964 are factors. In this case, the quotient is a whole number. Write them in the table inside the other two factors like the below example. Don't forget to write the negative numbers too!

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

1 2 80,964 161,928
-1 -2 -80,964 -161,928

Now, we try dividing 161,928 by 3:

161,928 ÷ 3 = 53,976

If the quotient is a whole number, then 3 and 53,976 are factors. In this case, the quotient is a whole number. Write them in the table inside the other two factors like the below example. Don't forget to write the negative numbers too!

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

1 2 3 53,976 80,964 161,928
-1 -2 -3 -53,976 -80,964 -161,928

Let's try dividing by 4:

161,928 ÷ 4 = 40,482

If the quotient is a whole number, then 4 and 40,482 are factors. In this case, the quotient is a whole number. Write them in the table inside the other two factors like the below example. Don't forget to write the negative numbers too!

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

1 2 3 4 40,482 53,976 80,964 161,928
-1 -2 -3 -4 -40,482 -53,976 -80,964 161,928
Keep dividing by the next highest number until you cannot divide anymore.

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