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 11,047,687, 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 | 11,047,687 | |
| -1 | -11,047,687 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 11,047,687.
Example:
1 x 11,047,687 = 11,047,687
and
-1 x -11,047,687 = 11,047,687
Notice both answers equal 11,047,687
With that explanation out of the way, let's continue. Next, we take the number 11,047,687 and divide it by 2:
11,047,687 ÷ 2 = 5,523,843.5
If the quotient is a whole number, then 2 and 5,523,843.5 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 | 11,047,687 | |
| -1 | -11,047,687 |
Now, we try dividing 11,047,687 by 3:
11,047,687 ÷ 3 = 3,682,562.3333
If the quotient is a whole number, then 3 and 3,682,562.3333 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 | 11,047,687 | |
| -1 | -11,047,687 |
Let's try dividing by 4:
11,047,687 ÷ 4 = 2,761,921.75
If the quotient is a whole number, then 4 and 2,761,921.75 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 | 11,047,687 | |
| -1 | 11,047,687 |
If you did it right, you will end up with this table:
| 1 | 7 | 31 | 49 | 217 | 343 | 1,039 | 1,519 | 7,273 | 10,633 | 32,209 | 50,911 | 225,463 | 356,377 | 1,578,241 | 11,047,687 |
| -1 | -7 | -31 | -49 | -217 | -343 | -1,039 | -1,519 | -7,273 | -10,633 | -32,209 | -50,911 | -225,463 | -356,377 | -1,578,241 | -11,047,687 |
