How do I find the factor combinations of the number 11,000,011?

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 11,000,011, 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 11,000,011
-1 -11,000,011

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 11,000,011.

Example:
1 x 11,000,011 = 11,000,011
and
-1 x -11,000,011 = 11,000,011
Notice both answers equal 11,000,011

With that explanation out of the way, let's continue. Next, we take the number 11,000,011 and divide it by 2:

11,000,011 ÷ 2 = 5,500,005.5

If the quotient is a whole number, then 2 and 5,500,005.5 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 11,000,011
-1 -11,000,011

Now, we try dividing 11,000,011 by 3:

11,000,011 ÷ 3 = 3,666,670.3333

If the quotient is a whole number, then 3 and 3,666,670.3333 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 11,000,011
-1 -11,000,011

Let's try dividing by 4:

11,000,011 ÷ 4 = 2,750,002.75

If the quotient is a whole number, then 4 and 2,750,002.75 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 11,000,011
-1 11,000,011
Keep dividing by the next highest number until you cannot divide anymore.

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

1111011,1119,901108,9111,000,00111,000,011
-1-11-101-1,111-9,901-108,911-1,000,001-11,000,011
