How do I find the factor combinations of the number 11,033,149?

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 11,033,149, 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 11,033,149
-1 -11,033,149

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 11,033,149.

Example:
1 x 11,033,149 = 11,033,149
and
-1 x -11,033,149 = 11,033,149
Notice both answers equal 11,033,149

With that explanation out of the way, let's continue. Next, we take the number 11,033,149 and divide it by 2:

11,033,149 ÷ 2 = 5,516,574.5

If the quotient is a whole number, then 2 and 5,516,574.5 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 11,033,149
-1 -11,033,149

Now, we try dividing 11,033,149 by 3:

11,033,149 ÷ 3 = 3,677,716.3333

If the quotient is a whole number, then 3 and 3,677,716.3333 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 11,033,149
-1 -11,033,149

Let's try dividing by 4:

11,033,149 ÷ 4 = 2,758,287.25

If the quotient is a whole number, then 4 and 2,758,287.25 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 11,033,149
-1 11,033,149
Keep dividing by the next highest number until you cannot divide anymore.

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

11,06910,32111,033,149
-1-1,069-10,321-11,033,149
