How do I find the factor combinations of the number 458,459?

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 458,459, 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.

1 458,459
-1 -458,459

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 458,459.

Example:
1 x 458,459 = 458,459
and
-1 x -458,459 = 458,459
Notice both answers equal 458,459

With that explanation out of the way, let's continue. Next, we take the number 458,459 and divide it by 2:

458,459 ÷ 2 = 229,229.5

If the quotient is a whole number, then 2 and 229,229.5 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:

1 458,459
-1 -458,459

Now, we try dividing 458,459 by 3:

458,459 ÷ 3 = 152,819.6667

If the quotient is a whole number, then 3 and 152,819.6667 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:

1 458,459
-1 -458,459

Let's try dividing by 4:

458,459 ÷ 4 = 114,614.75

If the quotient is a whole number, then 4 and 114,614.75 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:

1 458,459
-1 458,459
Keep dividing by the next highest number until you cannot divide anymore.

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

1233164371314,78919,933458,459
-1-23-31-643-713-14,789-19,933-458,459
