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 23,016,805, 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 | 23,016,805 | |
| -1 | -23,016,805 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,016,805.
Example:
1 x 23,016,805 = 23,016,805
and
-1 x -23,016,805 = 23,016,805
Notice both answers equal 23,016,805
With that explanation out of the way, let's continue. Next, we take the number 23,016,805 and divide it by 2:
23,016,805 ÷ 2 = 11,508,402.5
If the quotient is a whole number, then 2 and 11,508,402.5 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 | 23,016,805 | |
| -1 | -23,016,805 |
Now, we try dividing 23,016,805 by 3:
23,016,805 ÷ 3 = 7,672,268.3333
If the quotient is a whole number, then 3 and 7,672,268.3333 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 | 23,016,805 | |
| -1 | -23,016,805 |
Let's try dividing by 4:
23,016,805 ÷ 4 = 5,754,201.25
If the quotient is a whole number, then 4 and 5,754,201.25 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 | 23,016,805 | |
| -1 | 23,016,805 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 457 | 1,439 | 2,285 | 3,199 | 7,195 | 10,073 | 15,995 | 50,365 | 657,623 | 3,288,115 | 4,603,361 | 23,016,805 |
| -1 | -5 | -7 | -35 | -457 | -1,439 | -2,285 | -3,199 | -7,195 | -10,073 | -15,995 | -50,365 | -657,623 | -3,288,115 | -4,603,361 | -23,016,805 |
