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 13,510,645, 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 | 13,510,645 | |
| -1 | -13,510,645 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,510,645.
Example:
1 x 13,510,645 = 13,510,645
and
-1 x -13,510,645 = 13,510,645
Notice both answers equal 13,510,645
With that explanation out of the way, let's continue. Next, we take the number 13,510,645 and divide it by 2:
13,510,645 ÷ 2 = 6,755,322.5
If the quotient is a whole number, then 2 and 6,755,322.5 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 | 13,510,645 | |
| -1 | -13,510,645 |
Now, we try dividing 13,510,645 by 3:
13,510,645 ÷ 3 = 4,503,548.3333
If the quotient is a whole number, then 3 and 4,503,548.3333 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 | 13,510,645 | |
| -1 | -13,510,645 |
Let's try dividing by 4:
13,510,645 ÷ 4 = 3,377,661.25
If the quotient is a whole number, then 4 and 3,377,661.25 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 | 13,510,645 | |
| -1 | 13,510,645 |
If you did it right, you will end up with this table:
| 1 | 5 | 89 | 97 | 313 | 445 | 485 | 1,565 | 8,633 | 27,857 | 30,361 | 43,165 | 139,285 | 151,805 | 2,702,129 | 13,510,645 |
| -1 | -5 | -89 | -97 | -313 | -445 | -485 | -1,565 | -8,633 | -27,857 | -30,361 | -43,165 | -139,285 | -151,805 | -2,702,129 | -13,510,645 |
