How do I find the factor combinations of the number 19,733?

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 19,733, 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 19,733
-1 -19,733

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 19,733.

Example:
1 x 19,733 = 19,733
and
-1 x -19,733 = 19,733
Notice both answers equal 19,733

With that explanation out of the way, let's continue. Next, we take the number 19,733 and divide it by 2:

19,733 ÷ 2 = 9,866.5

If the quotient is a whole number, then 2 and 9,866.5 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 19,733
-1 -19,733

Now, we try dividing 19,733 by 3:

19,733 ÷ 3 = 6,577.6667

If the quotient is a whole number, then 3 and 6,577.6667 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 19,733
-1 -19,733

Let's try dividing by 4:

19,733 ÷ 4 = 4,933.25

If the quotient is a whole number, then 4 and 4,933.25 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 19,733
-1 19,733
Keep dividing by the next highest number until you cannot divide anymore.

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

172,81919,733
-1-7-2,819-19,733
