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 115,066,265, 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 | 115,066,265 | |
| -1 | -115,066,265 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 115,066,265.
Example:
1 x 115,066,265 = 115,066,265
and
-1 x -115,066,265 = 115,066,265
Notice both answers equal 115,066,265
With that explanation out of the way, let's continue. Next, we take the number 115,066,265 and divide it by 2:
115,066,265 ÷ 2 = 57,533,132.5
If the quotient is a whole number, then 2 and 57,533,132.5 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 | 115,066,265 | |
| -1 | -115,066,265 |
Now, we try dividing 115,066,265 by 3:
115,066,265 ÷ 3 = 38,355,421.6667
If the quotient is a whole number, then 3 and 38,355,421.6667 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 | 115,066,265 | |
| -1 | -115,066,265 |
Let's try dividing by 4:
115,066,265 ÷ 4 = 28,766,566.25
If the quotient is a whole number, then 4 and 28,766,566.25 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 | 115,066,265 | |
| -1 | 115,066,265 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 79 | 155 | 395 | 2,449 | 9,397 | 12,245 | 46,985 | 291,307 | 742,363 | 1,456,535 | 3,711,815 | 23,013,253 | 115,066,265 |
| -1 | -5 | -31 | -79 | -155 | -395 | -2,449 | -9,397 | -12,245 | -46,985 | -291,307 | -742,363 | -1,456,535 | -3,711,815 | -23,013,253 | -115,066,265 |
