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 13,886,365, 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 | 13,886,365 | |
| -1 | -13,886,365 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,886,365.
Example:
1 x 13,886,365 = 13,886,365
and
-1 x -13,886,365 = 13,886,365
Notice both answers equal 13,886,365
With that explanation out of the way, let's continue. Next, we take the number 13,886,365 and divide it by 2:
13,886,365 ÷ 2 = 6,943,182.5
If the quotient is a whole number, then 2 and 6,943,182.5 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 | 13,886,365 | |
| -1 | -13,886,365 |
Now, we try dividing 13,886,365 by 3:
13,886,365 ÷ 3 = 4,628,788.3333
If the quotient is a whole number, then 3 and 4,628,788.3333 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 | 13,886,365 | |
| -1 | -13,886,365 |
Let's try dividing by 4:
13,886,365 ÷ 4 = 3,471,591.25
If the quotient is a whole number, then 4 and 3,471,591.25 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 | 13,886,365 | |
| -1 | 13,886,365 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 23 | 85 | 115 | 391 | 1,955 | 7,103 | 35,515 | 120,751 | 163,369 | 603,755 | 816,845 | 2,777,273 | 13,886,365 |
| -1 | -5 | -17 | -23 | -85 | -115 | -391 | -1,955 | -7,103 | -35,515 | -120,751 | -163,369 | -603,755 | -816,845 | -2,777,273 | -13,886,365 |
