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 24,324,145, 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 | 24,324,145 | |
| -1 | -24,324,145 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 24,324,145.
Example:
1 x 24,324,145 = 24,324,145
and
-1 x -24,324,145 = 24,324,145
Notice both answers equal 24,324,145
With that explanation out of the way, let's continue. Next, we take the number 24,324,145 and divide it by 2:
24,324,145 ÷ 2 = 12,162,072.5
If the quotient is a whole number, then 2 and 12,162,072.5 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 | 24,324,145 | |
| -1 | -24,324,145 |
Now, we try dividing 24,324,145 by 3:
24,324,145 ÷ 3 = 8,108,048.3333
If the quotient is a whole number, then 3 and 8,108,048.3333 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 | 24,324,145 | |
| -1 | -24,324,145 |
Let's try dividing by 4:
24,324,145 ÷ 4 = 6,081,036.25
If the quotient is a whole number, then 4 and 6,081,036.25 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 | 24,324,145 | |
| -1 | 24,324,145 |
If you did it right, you will end up with this table:
| 1 | 5 | 47 | 89 | 235 | 445 | 1,163 | 4,183 | 5,815 | 20,915 | 54,661 | 103,507 | 273,305 | 517,535 | 4,864,829 | 24,324,145 |
| -1 | -5 | -47 | -89 | -235 | -445 | -1,163 | -4,183 | -5,815 | -20,915 | -54,661 | -103,507 | -273,305 | -517,535 | -4,864,829 | -24,324,145 |
