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 115,115, 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 | 115,115 | |
| -1 | -115,115 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 115,115.
Example:
1 x 115,115 = 115,115
and
-1 x -115,115 = 115,115
Notice both answers equal 115,115
With that explanation out of the way, let's continue. Next, we take the number 115,115 and divide it by 2:
115,115 ÷ 2 = 57,557.5
If the quotient is a whole number, then 2 and 57,557.5 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 | 115,115 | |
| -1 | -115,115 |
Now, we try dividing 115,115 by 3:
115,115 ÷ 3 = 38,371.6667
If the quotient is a whole number, then 3 and 38,371.6667 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 | 115,115 | |
| -1 | -115,115 |
Let's try dividing by 4:
115,115 ÷ 4 = 28,778.75
If the quotient is a whole number, then 4 and 28,778.75 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 | 115,115 | |
| -1 | 115,115 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 11 | 13 | 23 | 35 | 55 | 65 | 77 | 91 | 115 | 143 | 161 | 253 | 299 | 385 | 455 | 715 | 805 | 1,001 | 1,265 | 1,495 | 1,771 | 2,093 | 3,289 | 5,005 | 8,855 | 10,465 | 16,445 | 23,023 | 115,115 |
| -1 | -5 | -7 | -11 | -13 | -23 | -35 | -55 | -65 | -77 | -91 | -115 | -143 | -161 | -253 | -299 | -385 | -455 | -715 | -805 | -1,001 | -1,265 | -1,495 | -1,771 | -2,093 | -3,289 | -5,005 | -8,855 | -10,465 | -16,445 | -23,023 | -115,115 |
