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 10,013,645, 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 | 10,013,645 | |
| -1 | -10,013,645 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,013,645.
Example:
1 x 10,013,645 = 10,013,645
and
-1 x -10,013,645 = 10,013,645
Notice both answers equal 10,013,645
With that explanation out of the way, let's continue. Next, we take the number 10,013,645 and divide it by 2:
10,013,645 ÷ 2 = 5,006,822.5
If the quotient is a whole number, then 2 and 5,006,822.5 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 | 10,013,645 | |
| -1 | -10,013,645 |
Now, we try dividing 10,013,645 by 3:
10,013,645 ÷ 3 = 3,337,881.6667
If the quotient is a whole number, then 3 and 3,337,881.6667 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 | 10,013,645 | |
| -1 | -10,013,645 |
Let's try dividing by 4:
10,013,645 ÷ 4 = 2,503,411.25
If the quotient is a whole number, then 4 and 2,503,411.25 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 | 10,013,645 | |
| -1 | 10,013,645 |
If you did it right, you will end up with this table:
| 1 | 5 | 79 | 101 | 251 | 395 | 505 | 1,255 | 7,979 | 19,829 | 25,351 | 39,895 | 99,145 | 126,755 | 2,002,729 | 10,013,645 |
| -1 | -5 | -79 | -101 | -251 | -395 | -505 | -1,255 | -7,979 | -19,829 | -25,351 | -39,895 | -99,145 | -126,755 | -2,002,729 | -10,013,645 |
