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 48,087,325, 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 | 48,087,325 | |
| -1 | -48,087,325 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 48,087,325.
Example:
1 x 48,087,325 = 48,087,325
and
-1 x -48,087,325 = 48,087,325
Notice both answers equal 48,087,325
With that explanation out of the way, let's continue. Next, we take the number 48,087,325 and divide it by 2:
48,087,325 ÷ 2 = 24,043,662.5
If the quotient is a whole number, then 2 and 24,043,662.5 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 | 48,087,325 | |
| -1 | -48,087,325 |
Now, we try dividing 48,087,325 by 3:
48,087,325 ÷ 3 = 16,029,108.3333
If the quotient is a whole number, then 3 and 16,029,108.3333 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 | 48,087,325 | |
| -1 | -48,087,325 |
Let's try dividing by 4:
48,087,325 ÷ 4 = 12,021,831.25
If the quotient is a whole number, then 4 and 12,021,831.25 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 | 48,087,325 | |
| -1 | 48,087,325 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 13 | 25 | 55 | 65 | 143 | 275 | 325 | 715 | 3,575 | 13,451 | 67,255 | 147,961 | 174,863 | 336,275 | 739,805 | 874,315 | 1,923,493 | 3,699,025 | 4,371,575 | 9,617,465 | 48,087,325 |
| -1 | -5 | -11 | -13 | -25 | -55 | -65 | -143 | -275 | -325 | -715 | -3,575 | -13,451 | -67,255 | -147,961 | -174,863 | -336,275 | -739,805 | -874,315 | -1,923,493 | -3,699,025 | -4,371,575 | -9,617,465 | -48,087,325 |
