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 115,213,535, 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 | 115,213,535 | |
| -1 | -115,213,535 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 115,213,535.
Example:
1 x 115,213,535 = 115,213,535
and
-1 x -115,213,535 = 115,213,535
Notice both answers equal 115,213,535
With that explanation out of the way, let's continue. Next, we take the number 115,213,535 and divide it by 2:
115,213,535 ÷ 2 = 57,606,767.5
If the quotient is a whole number, then 2 and 57,606,767.5 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 | 115,213,535 | |
| -1 | -115,213,535 |
Now, we try dividing 115,213,535 by 3:
115,213,535 ÷ 3 = 38,404,511.6667
If the quotient is a whole number, then 3 and 38,404,511.6667 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 | 115,213,535 | |
| -1 | -115,213,535 |
Let's try dividing by 4:
115,213,535 ÷ 4 = 28,803,383.75
If the quotient is a whole number, then 4 and 28,803,383.75 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 | 115,213,535 | |
| -1 | 115,213,535 |
If you did it right, you will end up with this table:
| 1 | 5 | 67 | 239 | 335 | 1,195 | 1,439 | 7,195 | 16,013 | 80,065 | 96,413 | 343,921 | 482,065 | 1,719,605 | 23,042,707 | 115,213,535 |
| -1 | -5 | -67 | -239 | -335 | -1,195 | -1,439 | -7,195 | -16,013 | -80,065 | -96,413 | -343,921 | -482,065 | -1,719,605 | -23,042,707 | -115,213,535 |
