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 24,884,069, 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 | 24,884,069 | |
| -1 | -24,884,069 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 24,884,069.
Example:
1 x 24,884,069 = 24,884,069
and
-1 x -24,884,069 = 24,884,069
Notice both answers equal 24,884,069
With that explanation out of the way, let's continue. Next, we take the number 24,884,069 and divide it by 2:
24,884,069 ÷ 2 = 12,442,034.5
If the quotient is a whole number, then 2 and 12,442,034.5 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 | 24,884,069 | |
| -1 | -24,884,069 |
Now, we try dividing 24,884,069 by 3:
24,884,069 ÷ 3 = 8,294,689.6667
If the quotient is a whole number, then 3 and 8,294,689.6667 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 | 24,884,069 | |
| -1 | -24,884,069 |
Let's try dividing by 4:
24,884,069 ÷ 4 = 6,221,017.25
If the quotient is a whole number, then 4 and 6,221,017.25 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 | 24,884,069 | |
| -1 | 24,884,069 |
If you did it right, you will end up with this table:
| 1 | 7 | 113 | 163 | 193 | 791 | 1,141 | 1,351 | 18,419 | 21,809 | 31,459 | 128,933 | 152,663 | 220,213 | 3,554,867 | 24,884,069 |
| -1 | -7 | -113 | -163 | -193 | -791 | -1,141 | -1,351 | -18,419 | -21,809 | -31,459 | -128,933 | -152,663 | -220,213 | -3,554,867 | -24,884,069 |
