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 16,234,813, 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 | 16,234,813 | |
| -1 | -16,234,813 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,234,813.
Example:
1 x 16,234,813 = 16,234,813
and
-1 x -16,234,813 = 16,234,813
Notice both answers equal 16,234,813
With that explanation out of the way, let's continue. Next, we take the number 16,234,813 and divide it by 2:
16,234,813 ÷ 2 = 8,117,406.5
If the quotient is a whole number, then 2 and 8,117,406.5 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 | 16,234,813 | |
| -1 | -16,234,813 |
Now, we try dividing 16,234,813 by 3:
16,234,813 ÷ 3 = 5,411,604.3333
If the quotient is a whole number, then 3 and 5,411,604.3333 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 | 16,234,813 | |
| -1 | -16,234,813 |
Let's try dividing by 4:
16,234,813 ÷ 4 = 4,058,703.25
If the quotient is a whole number, then 4 and 4,058,703.25 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 | 16,234,813 | |
| -1 | 16,234,813 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 119 | 227 | 601 | 1,589 | 3,859 | 4,207 | 10,217 | 27,013 | 71,519 | 136,427 | 954,989 | 2,319,259 | 16,234,813 |
| -1 | -7 | -17 | -119 | -227 | -601 | -1,589 | -3,859 | -4,207 | -10,217 | -27,013 | -71,519 | -136,427 | -954,989 | -2,319,259 | -16,234,813 |
