How do I find the factor combinations of the number 259,363?

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 259,363, 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.

1 259,363
-1 -259,363

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 259,363.

Example:
1 x 259,363 = 259,363
and
-1 x -259,363 = 259,363
Notice both answers equal 259,363

With that explanation out of the way, let's continue. Next, we take the number 259,363 and divide it by 2:

259,363 ÷ 2 = 129,681.5

If the quotient is a whole number, then 2 and 129,681.5 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:

1 259,363
-1 -259,363

Now, we try dividing 259,363 by 3:

259,363 ÷ 3 = 86,454.3333

If the quotient is a whole number, then 3 and 86,454.3333 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:

1 259,363
-1 -259,363

Let's try dividing by 4:

259,363 ÷ 4 = 64,840.75

If the quotient is a whole number, then 4 and 64,840.75 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:

1 259,363
-1 259,363
Keep dividing by the next highest number until you cannot divide anymore.

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

113712819233,65319,951259,363
-1-13-71-281-923-3,653-19,951-259,363
