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 14,680,685, 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 | 14,680,685 | |
| -1 | -14,680,685 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 14,680,685.
Example:
1 x 14,680,685 = 14,680,685
and
-1 x -14,680,685 = 14,680,685
Notice both answers equal 14,680,685
With that explanation out of the way, let's continue. Next, we take the number 14,680,685 and divide it by 2:
14,680,685 ÷ 2 = 7,340,342.5
If the quotient is a whole number, then 2 and 7,340,342.5 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 | 14,680,685 | |
| -1 | -14,680,685 |
Now, we try dividing 14,680,685 by 3:
14,680,685 ÷ 3 = 4,893,561.6667
If the quotient is a whole number, then 3 and 4,893,561.6667 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 | 14,680,685 | |
| -1 | -14,680,685 |
Let's try dividing by 4:
14,680,685 ÷ 4 = 3,670,171.25
If the quotient is a whole number, then 4 and 3,670,171.25 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 | 14,680,685 | |
| -1 | 14,680,685 |
If you did it right, you will end up with this table:
| 1 | 5 | 47 | 179 | 235 | 349 | 895 | 1,745 | 8,413 | 16,403 | 42,065 | 62,471 | 82,015 | 312,355 | 2,936,137 | 14,680,685 |
| -1 | -5 | -47 | -179 | -235 | -349 | -895 | -1,745 | -8,413 | -16,403 | -42,065 | -62,471 | -82,015 | -312,355 | -2,936,137 | -14,680,685 |
