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 15,004,405, 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 | 15,004,405 | |
| -1 | -15,004,405 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 15,004,405.
Example:
1 x 15,004,405 = 15,004,405
and
-1 x -15,004,405 = 15,004,405
Notice both answers equal 15,004,405
With that explanation out of the way, let's continue. Next, we take the number 15,004,405 and divide it by 2:
15,004,405 ÷ 2 = 7,502,202.5
If the quotient is a whole number, then 2 and 7,502,202.5 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 | 15,004,405 | |
| -1 | -15,004,405 |
Now, we try dividing 15,004,405 by 3:
15,004,405 ÷ 3 = 5,001,468.3333
If the quotient is a whole number, then 3 and 5,001,468.3333 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 | 15,004,405 | |
| -1 | -15,004,405 |
Let's try dividing by 4:
15,004,405 ÷ 4 = 3,751,101.25
If the quotient is a whole number, then 4 and 3,751,101.25 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 | 15,004,405 | |
| -1 | 15,004,405 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 359 | 643 | 1,795 | 3,215 | 4,667 | 8,359 | 23,335 | 41,795 | 230,837 | 1,154,185 | 3,000,881 | 15,004,405 |
| -1 | -5 | -13 | -65 | -359 | -643 | -1,795 | -3,215 | -4,667 | -8,359 | -23,335 | -41,795 | -230,837 | -1,154,185 | -3,000,881 | -15,004,405 |
