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 24,213,305, 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 | 24,213,305 | |
| -1 | -24,213,305 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 24,213,305.
Example:
1 x 24,213,305 = 24,213,305
and
-1 x -24,213,305 = 24,213,305
Notice both answers equal 24,213,305
With that explanation out of the way, let's continue. Next, we take the number 24,213,305 and divide it by 2:
24,213,305 ÷ 2 = 12,106,652.5
If the quotient is a whole number, then 2 and 12,106,652.5 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 | 24,213,305 | |
| -1 | -24,213,305 |
Now, we try dividing 24,213,305 by 3:
24,213,305 ÷ 3 = 8,071,101.6667
If the quotient is a whole number, then 3 and 8,071,101.6667 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 | 24,213,305 | |
| -1 | -24,213,305 |
Let's try dividing by 4:
24,213,305 ÷ 4 = 6,053,326.25
If the quotient is a whole number, then 4 and 6,053,326.25 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 | 24,213,305 | |
| -1 | 24,213,305 |
If you did it right, you will end up with this table:
| 1 | 5 | 59 | 211 | 295 | 389 | 1,055 | 1,945 | 12,449 | 22,951 | 62,245 | 82,079 | 114,755 | 410,395 | 4,842,661 | 24,213,305 |
| -1 | -5 | -59 | -211 | -295 | -389 | -1,055 | -1,945 | -12,449 | -22,951 | -62,245 | -82,079 | -114,755 | -410,395 | -4,842,661 | -24,213,305 |
