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 14,203,115, 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 | 14,203,115 | |
| -1 | -14,203,115 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 14,203,115.
Example:
1 x 14,203,115 = 14,203,115
and
-1 x -14,203,115 = 14,203,115
Notice both answers equal 14,203,115
With that explanation out of the way, let's continue. Next, we take the number 14,203,115 and divide it by 2:
14,203,115 ÷ 2 = 7,101,557.5
If the quotient is a whole number, then 2 and 7,101,557.5 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 | 14,203,115 | |
| -1 | -14,203,115 |
Now, we try dividing 14,203,115 by 3:
14,203,115 ÷ 3 = 4,734,371.6667
If the quotient is a whole number, then 3 and 4,734,371.6667 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 | 14,203,115 | |
| -1 | -14,203,115 |
Let's try dividing by 4:
14,203,115 ÷ 4 = 3,550,778.75
If the quotient is a whole number, then 4 and 3,550,778.75 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 | 14,203,115 | |
| -1 | 14,203,115 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 43 | 155 | 215 | 1,333 | 2,131 | 6,665 | 10,655 | 66,061 | 91,633 | 330,305 | 458,165 | 2,840,623 | 14,203,115 |
| -1 | -5 | -31 | -43 | -155 | -215 | -1,333 | -2,131 | -6,665 | -10,655 | -66,061 | -91,633 | -330,305 | -458,165 | -2,840,623 | -14,203,115 |
