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 14,789,225, 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 | 14,789,225 | |
| -1 | -14,789,225 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 14,789,225.
Example:
1 x 14,789,225 = 14,789,225
and
-1 x -14,789,225 = 14,789,225
Notice both answers equal 14,789,225
With that explanation out of the way, let's continue. Next, we take the number 14,789,225 and divide it by 2:
14,789,225 ÷ 2 = 7,394,612.5
If the quotient is a whole number, then 2 and 7,394,612.5 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 | 14,789,225 | |
| -1 | -14,789,225 |
Now, we try dividing 14,789,225 by 3:
14,789,225 ÷ 3 = 4,929,741.6667
If the quotient is a whole number, then 3 and 4,929,741.6667 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 | 14,789,225 | |
| -1 | -14,789,225 |
Let's try dividing by 4:
14,789,225 ÷ 4 = 3,697,306.25
If the quotient is a whole number, then 4 and 3,697,306.25 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 | 14,789,225 | |
| -1 | 14,789,225 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 55 | 121 | 275 | 605 | 3,025 | 4,889 | 24,445 | 53,779 | 122,225 | 268,895 | 591,569 | 1,344,475 | 2,957,845 | 14,789,225 |
| -1 | -5 | -11 | -25 | -55 | -121 | -275 | -605 | -3,025 | -4,889 | -24,445 | -53,779 | -122,225 | -268,895 | -591,569 | -1,344,475 | -2,957,845 | -14,789,225 |
