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 48,960,125, 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 | 48,960,125 | |
| -1 | -48,960,125 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 48,960,125.
Example:
1 x 48,960,125 = 48,960,125
and
-1 x -48,960,125 = 48,960,125
Notice both answers equal 48,960,125
With that explanation out of the way, let's continue. Next, we take the number 48,960,125 and divide it by 2:
48,960,125 ÷ 2 = 24,480,062.5
If the quotient is a whole number, then 2 and 24,480,062.5 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 | 48,960,125 | |
| -1 | -48,960,125 |
Now, we try dividing 48,960,125 by 3:
48,960,125 ÷ 3 = 16,320,041.6667
If the quotient is a whole number, then 3 and 16,320,041.6667 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 | 48,960,125 | |
| -1 | -48,960,125 |
Let's try dividing by 4:
48,960,125 ÷ 4 = 12,240,031.25
If the quotient is a whole number, then 4 and 12,240,031.25 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 | 48,960,125 | |
| -1 | 48,960,125 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 61 | 125 | 305 | 1,525 | 6,421 | 7,625 | 32,105 | 160,525 | 391,681 | 802,625 | 1,958,405 | 9,792,025 | 48,960,125 |
| -1 | -5 | -25 | -61 | -125 | -305 | -1,525 | -6,421 | -7,625 | -32,105 | -160,525 | -391,681 | -802,625 | -1,958,405 | -9,792,025 | -48,960,125 |
