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 24,125,915, 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 | 24,125,915 | |
| -1 | -24,125,915 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 24,125,915.
Example:
1 x 24,125,915 = 24,125,915
and
-1 x -24,125,915 = 24,125,915
Notice both answers equal 24,125,915
With that explanation out of the way, let's continue. Next, we take the number 24,125,915 and divide it by 2:
24,125,915 ÷ 2 = 12,062,957.5
If the quotient is a whole number, then 2 and 12,062,957.5 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 | 24,125,915 | |
| -1 | -24,125,915 |
Now, we try dividing 24,125,915 by 3:
24,125,915 ÷ 3 = 8,041,971.6667
If the quotient is a whole number, then 3 and 8,041,971.6667 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 | 24,125,915 | |
| -1 | -24,125,915 |
Let's try dividing by 4:
24,125,915 ÷ 4 = 6,031,478.75
If the quotient is a whole number, then 4 and 6,031,478.75 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 | 24,125,915 | |
| -1 | 24,125,915 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 19 | 55 | 95 | 209 | 1,045 | 23,087 | 115,435 | 253,957 | 438,653 | 1,269,785 | 2,193,265 | 4,825,183 | 24,125,915 |
| -1 | -5 | -11 | -19 | -55 | -95 | -209 | -1,045 | -23,087 | -115,435 | -253,957 | -438,653 | -1,269,785 | -2,193,265 | -4,825,183 | -24,125,915 |
