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 14,725,145, 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 | 14,725,145 | |
| -1 | -14,725,145 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 14,725,145.
Example:
1 x 14,725,145 = 14,725,145
and
-1 x -14,725,145 = 14,725,145
Notice both answers equal 14,725,145
With that explanation out of the way, let's continue. Next, we take the number 14,725,145 and divide it by 2:
14,725,145 ÷ 2 = 7,362,572.5
If the quotient is a whole number, then 2 and 7,362,572.5 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 | 14,725,145 | |
| -1 | -14,725,145 |
Now, we try dividing 14,725,145 by 3:
14,725,145 ÷ 3 = 4,908,381.6667
If the quotient is a whole number, then 3 and 4,908,381.6667 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 | 14,725,145 | |
| -1 | -14,725,145 |
Let's try dividing by 4:
14,725,145 ÷ 4 = 3,681,286.25
If the quotient is a whole number, then 4 and 3,681,286.25 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 | 14,725,145 | |
| -1 | 14,725,145 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 191 | 907 | 955 | 3,247 | 4,535 | 15,419 | 16,235 | 77,095 | 173,237 | 866,185 | 2,945,029 | 14,725,145 |
| -1 | -5 | -17 | -85 | -191 | -907 | -955 | -3,247 | -4,535 | -15,419 | -16,235 | -77,095 | -173,237 | -866,185 | -2,945,029 | -14,725,145 |
