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 115,432,405, 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 | 115,432,405 | |
| -1 | -115,432,405 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 115,432,405.
Example:
1 x 115,432,405 = 115,432,405
and
-1 x -115,432,405 = 115,432,405
Notice both answers equal 115,432,405
With that explanation out of the way, let's continue. Next, we take the number 115,432,405 and divide it by 2:
115,432,405 ÷ 2 = 57,716,202.5
If the quotient is a whole number, then 2 and 57,716,202.5 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 | 115,432,405 | |
| -1 | -115,432,405 |
Now, we try dividing 115,432,405 by 3:
115,432,405 ÷ 3 = 38,477,468.3333
If the quotient is a whole number, then 3 and 38,477,468.3333 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 | 115,432,405 | |
| -1 | -115,432,405 |
Let's try dividing by 4:
115,432,405 ÷ 4 = 28,858,101.25
If the quotient is a whole number, then 4 and 28,858,101.25 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 | 115,432,405 | |
| -1 | 115,432,405 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 419 | 2,095 | 4,609 | 5,009 | 23,045 | 25,045 | 55,099 | 275,495 | 2,098,771 | 10,493,855 | 23,086,481 | 115,432,405 |
| -1 | -5 | -11 | -55 | -419 | -2,095 | -4,609 | -5,009 | -23,045 | -25,045 | -55,099 | -275,495 | -2,098,771 | -10,493,855 | -23,086,481 | -115,432,405 |
