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 10,413,205, 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 | 10,413,205 | |
| -1 | -10,413,205 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,413,205.
Example:
1 x 10,413,205 = 10,413,205
and
-1 x -10,413,205 = 10,413,205
Notice both answers equal 10,413,205
With that explanation out of the way, let's continue. Next, we take the number 10,413,205 and divide it by 2:
10,413,205 ÷ 2 = 5,206,602.5
If the quotient is a whole number, then 2 and 5,206,602.5 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 | 10,413,205 | |
| -1 | -10,413,205 |
Now, we try dividing 10,413,205 by 3:
10,413,205 ÷ 3 = 3,471,068.3333
If the quotient is a whole number, then 3 and 3,471,068.3333 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 | 10,413,205 | |
| -1 | -10,413,205 |
Let's try dividing by 4:
10,413,205 ÷ 4 = 2,603,301.25
If the quotient is a whole number, then 4 and 2,603,301.25 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 | 10,413,205 | |
| -1 | 10,413,205 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 59 | 295 | 649 | 3,209 | 3,245 | 16,045 | 35,299 | 176,495 | 189,331 | 946,655 | 2,082,641 | 10,413,205 |
| -1 | -5 | -11 | -55 | -59 | -295 | -649 | -3,209 | -3,245 | -16,045 | -35,299 | -176,495 | -189,331 | -946,655 | -2,082,641 | -10,413,205 |
