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 11,011,231, it is easier to work with a table - it's called factoring from the outside in.
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 | 11,011,231 | |
| -1 | -11,011,231 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 11,011,231.
Example:
1 x 11,011,231 = 11,011,231
and
-1 x -11,011,231 = 11,011,231
Notice both answers equal 11,011,231
With that explanation out of the way, let's continue. Next, we take the number 11,011,231 and divide it by 2:
11,011,231 ÷ 2 = 5,505,615.5
If the quotient is a whole number, then 2 and 5,505,615.5 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 | 11,011,231 | |
| -1 | -11,011,231 |
Now, we try dividing 11,011,231 by 3:
11,011,231 ÷ 3 = 3,670,410.3333
If the quotient is a whole number, then 3 and 3,670,410.3333 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 | 11,011,231 | |
| -1 | -11,011,231 |
Let's try dividing by 4:
11,011,231 ÷ 4 = 2,752,807.75
If the quotient is a whole number, then 4 and 2,752,807.75 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 | 11,011,231 | |
| -1 | 11,011,231 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 31 | 49 | 77 | 217 | 341 | 539 | 659 | 1,519 | 2,387 | 4,613 | 7,249 | 16,709 | 20,429 | 32,291 | 50,743 | 143,003 | 224,719 | 355,201 | 1,001,021 | 1,573,033 | 11,011,231 |
| -1 | -7 | -11 | -31 | -49 | -77 | -217 | -341 | -539 | -659 | -1,519 | -2,387 | -4,613 | -7,249 | -16,709 | -20,429 | -32,291 | -50,743 | -143,003 | -224,719 | -355,201 | -1,001,021 | -1,573,033 | -11,011,231 |
