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 24,004,019, 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 | 24,004,019 | |
| -1 | -24,004,019 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 24,004,019.
Example:
1 x 24,004,019 = 24,004,019
and
-1 x -24,004,019 = 24,004,019
Notice both answers equal 24,004,019
With that explanation out of the way, let's continue. Next, we take the number 24,004,019 and divide it by 2:
24,004,019 ÷ 2 = 12,002,009.5
If the quotient is a whole number, then 2 and 12,002,009.5 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 | 24,004,019 | |
| -1 | -24,004,019 |
Now, we try dividing 24,004,019 by 3:
24,004,019 ÷ 3 = 8,001,339.6667
If the quotient is a whole number, then 3 and 8,001,339.6667 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 | 24,004,019 | |
| -1 | -24,004,019 |
Let's try dividing by 4:
24,004,019 ÷ 4 = 6,001,004.75
If the quotient is a whole number, then 4 and 6,001,004.75 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 | 24,004,019 | |
| -1 | 24,004,019 |
If you did it right, you will end up with this table:
| 1 | 13 | 23 | 43 | 299 | 559 | 989 | 1,867 | 12,857 | 24,271 | 42,941 | 80,281 | 558,233 | 1,043,653 | 1,846,463 | 24,004,019 |
| -1 | -13 | -23 | -43 | -299 | -559 | -989 | -1,867 | -12,857 | -24,271 | -42,941 | -80,281 | -558,233 | -1,043,653 | -1,846,463 | -24,004,019 |
