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 15,034,415, 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 | 15,034,415 | |
| -1 | -15,034,415 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 15,034,415.
Example:
1 x 15,034,415 = 15,034,415
and
-1 x -15,034,415 = 15,034,415
Notice both answers equal 15,034,415
With that explanation out of the way, let's continue. Next, we take the number 15,034,415 and divide it by 2:
15,034,415 ÷ 2 = 7,517,207.5
If the quotient is a whole number, then 2 and 7,517,207.5 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 | 15,034,415 | |
| -1 | -15,034,415 |
Now, we try dividing 15,034,415 by 3:
15,034,415 ÷ 3 = 5,011,471.6667
If the quotient is a whole number, then 3 and 5,011,471.6667 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 | 15,034,415 | |
| -1 | -15,034,415 |
Let's try dividing by 4:
15,034,415 ÷ 4 = 3,758,603.75
If the quotient is a whole number, then 4 and 3,758,603.75 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 | 15,034,415 | |
| -1 | 15,034,415 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 19 | 55 | 95 | 209 | 1,045 | 14,387 | 71,935 | 158,257 | 273,353 | 791,285 | 1,366,765 | 3,006,883 | 15,034,415 |
| -1 | -5 | -11 | -19 | -55 | -95 | -209 | -1,045 | -14,387 | -71,935 | -158,257 | -273,353 | -791,285 | -1,366,765 | -3,006,883 | -15,034,415 |
