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 10,553,413, 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 | 10,553,413 | |
| -1 | -10,553,413 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,553,413.
Example:
1 x 10,553,413 = 10,553,413
and
-1 x -10,553,413 = 10,553,413
Notice both answers equal 10,553,413
With that explanation out of the way, let's continue. Next, we take the number 10,553,413 and divide it by 2:
10,553,413 ÷ 2 = 5,276,706.5
If the quotient is a whole number, then 2 and 5,276,706.5 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 | 10,553,413 | |
| -1 | -10,553,413 |
Now, we try dividing 10,553,413 by 3:
10,553,413 ÷ 3 = 3,517,804.3333
If the quotient is a whole number, then 3 and 3,517,804.3333 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 | 10,553,413 | |
| -1 | -10,553,413 |
Let's try dividing by 4:
10,553,413 ÷ 4 = 2,638,353.25
If the quotient is a whole number, then 4 and 2,638,353.25 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 | 10,553,413 | |
| -1 | 10,553,413 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 53 | 221 | 289 | 689 | 901 | 2,809 | 3,757 | 11,713 | 15,317 | 36,517 | 47,753 | 199,121 | 620,789 | 811,801 | 10,553,413 |
| -1 | -13 | -17 | -53 | -221 | -289 | -689 | -901 | -2,809 | -3,757 | -11,713 | -15,317 | -36,517 | -47,753 | -199,121 | -620,789 | -811,801 | -10,553,413 |
