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 111,325,313, 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 | 111,325,313 | |
| -1 | -111,325,313 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 111,325,313.
Example:
1 x 111,325,313 = 111,325,313
and
-1 x -111,325,313 = 111,325,313
Notice both answers equal 111,325,313
With that explanation out of the way, let's continue. Next, we take the number 111,325,313 and divide it by 2:
111,325,313 ÷ 2 = 55,662,656.5
If the quotient is a whole number, then 2 and 55,662,656.5 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 | 111,325,313 | |
| -1 | -111,325,313 |
Now, we try dividing 111,325,313 by 3:
111,325,313 ÷ 3 = 37,108,437.6667
If the quotient is a whole number, then 3 and 37,108,437.6667 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 | 111,325,313 | |
| -1 | -111,325,313 |
Let's try dividing by 4:
111,325,313 ÷ 4 = 27,831,328.25
If the quotient is a whole number, then 4 and 27,831,328.25 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 | 111,325,313 | |
| -1 | 111,325,313 |
If you did it right, you will end up with this table:
| 1 | 11 | 19 | 23 | 209 | 253 | 437 | 4,807 | 23,159 | 254,749 | 440,021 | 532,657 | 4,840,231 | 5,859,227 | 10,120,483 | 111,325,313 |
| -1 | -11 | -19 | -23 | -209 | -253 | -437 | -4,807 | -23,159 | -254,749 | -440,021 | -532,657 | -4,840,231 | -5,859,227 | -10,120,483 | -111,325,313 |
