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 23,661,869, 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 | 23,661,869 | |
| -1 | -23,661,869 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,661,869.
Example:
1 x 23,661,869 = 23,661,869
and
-1 x -23,661,869 = 23,661,869
Notice both answers equal 23,661,869
With that explanation out of the way, let's continue. Next, we take the number 23,661,869 and divide it by 2:
23,661,869 ÷ 2 = 11,830,934.5
If the quotient is a whole number, then 2 and 11,830,934.5 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 | 23,661,869 | |
| -1 | -23,661,869 |
Now, we try dividing 23,661,869 by 3:
23,661,869 ÷ 3 = 7,887,289.6667
If the quotient is a whole number, then 3 and 7,887,289.6667 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 | 23,661,869 | |
| -1 | -23,661,869 |
Let's try dividing by 4:
23,661,869 ÷ 4 = 5,915,467.25
If the quotient is a whole number, then 4 and 5,915,467.25 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 | 23,661,869 | |
| -1 | 23,661,869 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 487 | 631 | 3,409 | 4,417 | 5,357 | 6,941 | 37,499 | 48,587 | 307,297 | 2,151,079 | 3,380,267 | 23,661,869 |
| -1 | -7 | -11 | -77 | -487 | -631 | -3,409 | -4,417 | -5,357 | -6,941 | -37,499 | -48,587 | -307,297 | -2,151,079 | -3,380,267 | -23,661,869 |
