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 24,004,415, 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 | 24,004,415 | |
| -1 | -24,004,415 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 24,004,415.
Example:
1 x 24,004,415 = 24,004,415
and
-1 x -24,004,415 = 24,004,415
Notice both answers equal 24,004,415
With that explanation out of the way, let's continue. Next, we take the number 24,004,415 and divide it by 2:
24,004,415 ÷ 2 = 12,002,207.5
If the quotient is a whole number, then 2 and 12,002,207.5 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 | 24,004,415 | |
| -1 | -24,004,415 |
Now, we try dividing 24,004,415 by 3:
24,004,415 ÷ 3 = 8,001,471.6667
If the quotient is a whole number, then 3 and 8,001,471.6667 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 | 24,004,415 | |
| -1 | -24,004,415 |
Let's try dividing by 4:
24,004,415 ÷ 4 = 6,001,103.75
If the quotient is a whole number, then 4 and 6,001,103.75 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 | 24,004,415 | |
| -1 | 24,004,415 |
If you did it right, you will end up with this table:
| 1 | 5 | 61 | 211 | 305 | 373 | 1,055 | 1,865 | 12,871 | 22,753 | 64,355 | 78,703 | 113,765 | 393,515 | 4,800,883 | 24,004,415 |
| -1 | -5 | -61 | -211 | -305 | -373 | -1,055 | -1,865 | -12,871 | -22,753 | -64,355 | -78,703 | -113,765 | -393,515 | -4,800,883 | -24,004,415 |
