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 24,848,815, 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 | 24,848,815 | |
| -1 | -24,848,815 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 24,848,815.
Example:
1 x 24,848,815 = 24,848,815
and
-1 x -24,848,815 = 24,848,815
Notice both answers equal 24,848,815
With that explanation out of the way, let's continue. Next, we take the number 24,848,815 and divide it by 2:
24,848,815 ÷ 2 = 12,424,407.5
If the quotient is a whole number, then 2 and 12,424,407.5 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 | 24,848,815 | |
| -1 | -24,848,815 |
Now, we try dividing 24,848,815 by 3:
24,848,815 ÷ 3 = 8,282,938.3333
If the quotient is a whole number, then 3 and 8,282,938.3333 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 | 24,848,815 | |
| -1 | -24,848,815 |
Let's try dividing by 4:
24,848,815 ÷ 4 = 6,212,203.75
If the quotient is a whole number, then 4 and 6,212,203.75 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 | 24,848,815 | |
| -1 | 24,848,815 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 283 | 1,033 | 1,415 | 4,811 | 5,165 | 17,561 | 24,055 | 87,805 | 292,339 | 1,461,695 | 4,969,763 | 24,848,815 |
| -1 | -5 | -17 | -85 | -283 | -1,033 | -1,415 | -4,811 | -5,165 | -17,561 | -24,055 | -87,805 | -292,339 | -1,461,695 | -4,969,763 | -24,848,815 |
