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 15,010,415, 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 | 15,010,415 | |
| -1 | -15,010,415 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 15,010,415.
Example:
1 x 15,010,415 = 15,010,415
and
-1 x -15,010,415 = 15,010,415
Notice both answers equal 15,010,415
With that explanation out of the way, let's continue. Next, we take the number 15,010,415 and divide it by 2:
15,010,415 ÷ 2 = 7,505,207.5
If the quotient is a whole number, then 2 and 7,505,207.5 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 | 15,010,415 | |
| -1 | -15,010,415 |
Now, we try dividing 15,010,415 by 3:
15,010,415 ÷ 3 = 5,003,471.6667
If the quotient is a whole number, then 3 and 5,003,471.6667 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 | 15,010,415 | |
| -1 | -15,010,415 |
Let's try dividing by 4:
15,010,415 ÷ 4 = 3,752,603.75
If the quotient is a whole number, then 4 and 3,752,603.75 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 | 15,010,415 | |
| -1 | 15,010,415 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 49 | 197 | 245 | 311 | 985 | 1,379 | 1,555 | 2,177 | 6,895 | 9,653 | 10,885 | 15,239 | 48,265 | 61,267 | 76,195 | 306,335 | 428,869 | 2,144,345 | 3,002,083 | 15,010,415 |
| -1 | -5 | -7 | -35 | -49 | -197 | -245 | -311 | -985 | -1,379 | -1,555 | -2,177 | -6,895 | -9,653 | -10,885 | -15,239 | -48,265 | -61,267 | -76,195 | -306,335 | -428,869 | -2,144,345 | -3,002,083 | -15,010,415 |
