How do I find the factor combinations of the number 228,811?

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 228,811, 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.

1 228,811
-1 -228,811

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 228,811.

Example:
1 x 228,811 = 228,811
and
-1 x -228,811 = 228,811
Notice both answers equal 228,811

With that explanation out of the way, let's continue. Next, we take the number 228,811 and divide it by 2:

228,811 ÷ 2 = 114,405.5

If the quotient is a whole number, then 2 and 114,405.5 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:

1 228,811
-1 -228,811

Now, we try dividing 228,811 by 3:

228,811 ÷ 3 = 76,270.3333

If the quotient is a whole number, then 3 and 76,270.3333 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:

1 228,811
-1 -228,811

Let's try dividing by 4:

228,811 ÷ 4 = 57,202.75

If the quotient is a whole number, then 4 and 57,202.75 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:

1 228,811
-1 228,811
Keep dividing by the next highest number until you cannot divide anymore.

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

11131611213416711,8913,7517,38120,801228,811
-1-11-31-61-121-341-671-1,891-3,751-7,381-20,801-228,811
