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 14,585,915, 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 | 14,585,915 | |
| -1 | -14,585,915 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 14,585,915.
Example:
1 x 14,585,915 = 14,585,915
and
-1 x -14,585,915 = 14,585,915
Notice both answers equal 14,585,915
With that explanation out of the way, let's continue. Next, we take the number 14,585,915 and divide it by 2:
14,585,915 ÷ 2 = 7,292,957.5
If the quotient is a whole number, then 2 and 7,292,957.5 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 | 14,585,915 | |
| -1 | -14,585,915 |
Now, we try dividing 14,585,915 by 3:
14,585,915 ÷ 3 = 4,861,971.6667
If the quotient is a whole number, then 3 and 4,861,971.6667 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 | 14,585,915 | |
| -1 | -14,585,915 |
Let's try dividing by 4:
14,585,915 ÷ 4 = 3,646,478.75
If the quotient is a whole number, then 4 and 3,646,478.75 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 | 14,585,915 | |
| -1 | 14,585,915 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 101 | 505 | 1,699 | 1,717 | 8,495 | 8,585 | 28,883 | 144,415 | 171,599 | 857,995 | 2,917,183 | 14,585,915 |
| -1 | -5 | -17 | -85 | -101 | -505 | -1,699 | -1,717 | -8,495 | -8,585 | -28,883 | -144,415 | -171,599 | -857,995 | -2,917,183 | -14,585,915 |
