How do I find the factor combinations of the number 365,609?

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 365,609, 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.

1 365,609
-1 -365,609

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 365,609.

Example:
1 x 365,609 = 365,609
and
-1 x -365,609 = 365,609
Notice both answers equal 365,609

With that explanation out of the way, let's continue. Next, we take the number 365,609 and divide it by 2:

365,609 ÷ 2 = 182,804.5

If the quotient is a whole number, then 2 and 182,804.5 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:

1 365,609
-1 -365,609

Now, we try dividing 365,609 by 3:

365,609 ÷ 3 = 121,869.6667

If the quotient is a whole number, then 3 and 121,869.6667 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:

1 365,609
-1 -365,609

Let's try dividing by 4:

365,609 ÷ 4 = 91,402.25

If the quotient is a whole number, then 4 and 91,402.25 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:

1 365,609
-1 365,609
Keep dividing by the next highest number until you cannot divide anymore.

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

11632,243365,609
-1-163-2,243-365,609
