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 11,551,141, 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 | 11,551,141 | |
| -1 | -11,551,141 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 11,551,141.
Example:
1 x 11,551,141 = 11,551,141
and
-1 x -11,551,141 = 11,551,141
Notice both answers equal 11,551,141
With that explanation out of the way, let's continue. Next, we take the number 11,551,141 and divide it by 2:
11,551,141 ÷ 2 = 5,775,570.5
If the quotient is a whole number, then 2 and 5,775,570.5 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 | 11,551,141 | |
| -1 | -11,551,141 |
Now, we try dividing 11,551,141 by 3:
11,551,141 ÷ 3 = 3,850,380.3333
If the quotient is a whole number, then 3 and 3,850,380.3333 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 | 11,551,141 | |
| -1 | -11,551,141 |
Let's try dividing by 4:
11,551,141 ÷ 4 = 2,887,785.25
If the quotient is a whole number, then 4 and 2,887,785.25 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 | 11,551,141 | |
| -1 | 11,551,141 |
If you did it right, you will end up with this table:
| 1 | 7 | 37 | 103 | 259 | 433 | 721 | 3,031 | 3,811 | 16,021 | 26,677 | 44,599 | 112,147 | 312,193 | 1,650,163 | 11,551,141 |
| -1 | -7 | -37 | -103 | -259 | -433 | -721 | -3,031 | -3,811 | -16,021 | -26,677 | -44,599 | -112,147 | -312,193 | -1,650,163 | -11,551,141 |
