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 115,553,045, 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 | 115,553,045 | |
| -1 | -115,553,045 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 115,553,045.
Example:
1 x 115,553,045 = 115,553,045
and
-1 x -115,553,045 = 115,553,045
Notice both answers equal 115,553,045
With that explanation out of the way, let's continue. Next, we take the number 115,553,045 and divide it by 2:
115,553,045 ÷ 2 = 57,776,522.5
If the quotient is a whole number, then 2 and 57,776,522.5 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 | 115,553,045 | |
| -1 | -115,553,045 |
Now, we try dividing 115,553,045 by 3:
115,553,045 ÷ 3 = 38,517,681.6667
If the quotient is a whole number, then 3 and 38,517,681.6667 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 | 115,553,045 | |
| -1 | -115,553,045 |
Let's try dividing by 4:
115,553,045 ÷ 4 = 28,888,261.25
If the quotient is a whole number, then 4 and 28,888,261.25 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 | 115,553,045 | |
| -1 | 115,553,045 |
If you did it right, you will end up with this table:
| 1 | 5 | 107 | 271 | 535 | 797 | 1,355 | 3,985 | 28,997 | 85,279 | 144,985 | 215,987 | 426,395 | 1,079,935 | 23,110,609 | 115,553,045 |
| -1 | -5 | -107 | -271 | -535 | -797 | -1,355 | -3,985 | -28,997 | -85,279 | -144,985 | -215,987 | -426,395 | -1,079,935 | -23,110,609 | -115,553,045 |
