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 11,361,845, 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 | 11,361,845 | |
| -1 | -11,361,845 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 11,361,845.
Example:
1 x 11,361,845 = 11,361,845
and
-1 x -11,361,845 = 11,361,845
Notice both answers equal 11,361,845
With that explanation out of the way, let's continue. Next, we take the number 11,361,845 and divide it by 2:
11,361,845 ÷ 2 = 5,680,922.5
If the quotient is a whole number, then 2 and 5,680,922.5 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 | 11,361,845 | |
| -1 | -11,361,845 |
Now, we try dividing 11,361,845 by 3:
11,361,845 ÷ 3 = 3,787,281.6667
If the quotient is a whole number, then 3 and 3,787,281.6667 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 | 11,361,845 | |
| -1 | -11,361,845 |
Let's try dividing by 4:
11,361,845 ÷ 4 = 2,840,461.25
If the quotient is a whole number, then 4 and 2,840,461.25 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 | 11,361,845 | |
| -1 | 11,361,845 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 167 | 835 | 1,237 | 1,837 | 6,185 | 9,185 | 13,607 | 68,035 | 206,579 | 1,032,895 | 2,272,369 | 11,361,845 |
| -1 | -5 | -11 | -55 | -167 | -835 | -1,237 | -1,837 | -6,185 | -9,185 | -13,607 | -68,035 | -206,579 | -1,032,895 | -2,272,369 | -11,361,845 |
