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 111,111,325, 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 | 111,111,325 | |
| -1 | -111,111,325 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 111,111,325.
Example:
1 x 111,111,325 = 111,111,325
and
-1 x -111,111,325 = 111,111,325
Notice both answers equal 111,111,325
With that explanation out of the way, let's continue. Next, we take the number 111,111,325 and divide it by 2:
111,111,325 ÷ 2 = 55,555,662.5
If the quotient is a whole number, then 2 and 55,555,662.5 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 | 111,111,325 | |
| -1 | -111,111,325 |
Now, we try dividing 111,111,325 by 3:
111,111,325 ÷ 3 = 37,037,108.3333
If the quotient is a whole number, then 3 and 37,037,108.3333 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 | 111,111,325 | |
| -1 | -111,111,325 |
Let's try dividing by 4:
111,111,325 ÷ 4 = 27,777,831.25
If the quotient is a whole number, then 4 and 27,777,831.25 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 | 111,111,325 | |
| -1 | 111,111,325 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 25 | 29 | 65 | 145 | 325 | 377 | 725 | 1,885 | 9,425 | 11,789 | 58,945 | 153,257 | 294,725 | 341,881 | 766,285 | 1,709,405 | 3,831,425 | 4,444,453 | 8,547,025 | 22,222,265 | 111,111,325 |
| -1 | -5 | -13 | -25 | -29 | -65 | -145 | -325 | -377 | -725 | -1,885 | -9,425 | -11,789 | -58,945 | -153,257 | -294,725 | -341,881 | -766,285 | -1,709,405 | -3,831,425 | -4,444,453 | -8,547,025 | -22,222,265 | -111,111,325 |
