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 10,663,415, 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 | 10,663,415 | |
| -1 | -10,663,415 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,663,415.
Example:
1 x 10,663,415 = 10,663,415
and
-1 x -10,663,415 = 10,663,415
Notice both answers equal 10,663,415
With that explanation out of the way, let's continue. Next, we take the number 10,663,415 and divide it by 2:
10,663,415 ÷ 2 = 5,331,707.5
If the quotient is a whole number, then 2 and 5,331,707.5 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 | 10,663,415 | |
| -1 | -10,663,415 |
Now, we try dividing 10,663,415 by 3:
10,663,415 ÷ 3 = 3,554,471.6667
If the quotient is a whole number, then 3 and 3,554,471.6667 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 | 10,663,415 | |
| -1 | -10,663,415 |
Let's try dividing by 4:
10,663,415 ÷ 4 = 2,665,853.75
If the quotient is a whole number, then 4 and 2,665,853.75 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 | 10,663,415 | |
| -1 | 10,663,415 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 199 | 995 | 1,393 | 1,531 | 6,965 | 7,655 | 10,717 | 53,585 | 304,669 | 1,523,345 | 2,132,683 | 10,663,415 |
| -1 | -5 | -7 | -35 | -199 | -995 | -1,393 | -1,531 | -6,965 | -7,655 | -10,717 | -53,585 | -304,669 | -1,523,345 | -2,132,683 | -10,663,415 |
