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 325,540,105, 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 | 325,540,105 | |
| -1 | -325,540,105 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 325,540,105.
Example:
1 x 325,540,105 = 325,540,105
and
-1 x -325,540,105 = 325,540,105
Notice both answers equal 325,540,105
With that explanation out of the way, let's continue. Next, we take the number 325,540,105 and divide it by 2:
325,540,105 ÷ 2 = 162,770,052.5
If the quotient is a whole number, then 2 and 162,770,052.5 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 | 325,540,105 | |
| -1 | -325,540,105 |
Now, we try dividing 325,540,105 by 3:
325,540,105 ÷ 3 = 108,513,368.3333
If the quotient is a whole number, then 3 and 108,513,368.3333 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 | 325,540,105 | |
| -1 | -325,540,105 |
Let's try dividing by 4:
325,540,105 ÷ 4 = 81,385,026.25
If the quotient is a whole number, then 4 and 81,385,026.25 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 | 325,540,105 | |
| -1 | 325,540,105 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 271 | 1,355 | 2,981 | 14,905 | 21,841 | 109,205 | 240,251 | 1,201,255 | 5,918,911 | 29,594,555 | 65,108,021 | 325,540,105 |
| -1 | -5 | -11 | -55 | -271 | -1,355 | -2,981 | -14,905 | -21,841 | -109,205 | -240,251 | -1,201,255 | -5,918,911 | -29,594,555 | -65,108,021 | -325,540,105 |
