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 11,218,385, 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 | 11,218,385 | |
| -1 | -11,218,385 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 11,218,385.
Example:
1 x 11,218,385 = 11,218,385
and
-1 x -11,218,385 = 11,218,385
Notice both answers equal 11,218,385
With that explanation out of the way, let's continue. Next, we take the number 11,218,385 and divide it by 2:
11,218,385 ÷ 2 = 5,609,192.5
If the quotient is a whole number, then 2 and 5,609,192.5 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 | 11,218,385 | |
| -1 | -11,218,385 |
Now, we try dividing 11,218,385 by 3:
11,218,385 ÷ 3 = 3,739,461.6667
If the quotient is a whole number, then 3 and 3,739,461.6667 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 | 11,218,385 | |
| -1 | -11,218,385 |
Let's try dividing by 4:
11,218,385 ÷ 4 = 2,804,596.25
If the quotient is a whole number, then 4 and 2,804,596.25 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 | 11,218,385 | |
| -1 | 11,218,385 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 191 | 691 | 955 | 3,247 | 3,455 | 11,747 | 16,235 | 58,735 | 131,981 | 659,905 | 2,243,677 | 11,218,385 |
| -1 | -5 | -17 | -85 | -191 | -691 | -955 | -3,247 | -3,455 | -11,747 | -16,235 | -58,735 | -131,981 | -659,905 | -2,243,677 | -11,218,385 |
