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 24,002,321, 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 | 24,002,321 | |
| -1 | -24,002,321 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 24,002,321.
Example:
1 x 24,002,321 = 24,002,321
and
-1 x -24,002,321 = 24,002,321
Notice both answers equal 24,002,321
With that explanation out of the way, let's continue. Next, we take the number 24,002,321 and divide it by 2:
24,002,321 ÷ 2 = 12,001,160.5
If the quotient is a whole number, then 2 and 12,001,160.5 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 | 24,002,321 | |
| -1 | -24,002,321 |
Now, we try dividing 24,002,321 by 3:
24,002,321 ÷ 3 = 8,000,773.6667
If the quotient is a whole number, then 3 and 8,000,773.6667 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 | 24,002,321 | |
| -1 | -24,002,321 |
Let's try dividing by 4:
24,002,321 ÷ 4 = 6,000,580.25
If the quotient is a whole number, then 4 and 6,000,580.25 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 | 24,002,321 | |
| -1 | 24,002,321 |
If you did it right, you will end up with this table:
| 1 | 7 | 59 | 89 | 413 | 623 | 653 | 4,571 | 5,251 | 36,757 | 38,527 | 58,117 | 269,689 | 406,819 | 3,428,903 | 24,002,321 |
| -1 | -7 | -59 | -89 | -413 | -623 | -653 | -4,571 | -5,251 | -36,757 | -38,527 | -58,117 | -269,689 | -406,819 | -3,428,903 | -24,002,321 |
