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 15,240,109, 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 | 15,240,109 | |
| -1 | -15,240,109 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 15,240,109.
Example:
1 x 15,240,109 = 15,240,109
and
-1 x -15,240,109 = 15,240,109
Notice both answers equal 15,240,109
With that explanation out of the way, let's continue. Next, we take the number 15,240,109 and divide it by 2:
15,240,109 ÷ 2 = 7,620,054.5
If the quotient is a whole number, then 2 and 7,620,054.5 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 | 15,240,109 | |
| -1 | -15,240,109 |
Now, we try dividing 15,240,109 by 3:
15,240,109 ÷ 3 = 5,080,036.3333
If the quotient is a whole number, then 3 and 5,080,036.3333 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 | 15,240,109 | |
| -1 | -15,240,109 |
Let's try dividing by 4:
15,240,109 ÷ 4 = 3,810,027.25
If the quotient is a whole number, then 4 and 3,810,027.25 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 | 15,240,109 | |
| -1 | 15,240,109 |
If you did it right, you will end up with this table:
| 1 | 17 | 19 | 29 | 323 | 493 | 551 | 1,627 | 9,367 | 27,659 | 30,913 | 47,183 | 525,521 | 802,111 | 896,477 | 15,240,109 |
| -1 | -17 | -19 | -29 | -323 | -493 | -551 | -1,627 | -9,367 | -27,659 | -30,913 | -47,183 | -525,521 | -802,111 | -896,477 | -15,240,109 |
