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 130,027,165, 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 | 130,027,165 | |
| -1 | -130,027,165 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 130,027,165.
Example:
1 x 130,027,165 = 130,027,165
and
-1 x -130,027,165 = 130,027,165
Notice both answers equal 130,027,165
With that explanation out of the way, let's continue. Next, we take the number 130,027,165 and divide it by 2:
130,027,165 ÷ 2 = 65,013,582.5
If the quotient is a whole number, then 2 and 65,013,582.5 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 | 130,027,165 | |
| -1 | -130,027,165 |
Now, we try dividing 130,027,165 by 3:
130,027,165 ÷ 3 = 43,342,388.3333
If the quotient is a whole number, then 3 and 43,342,388.3333 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 | 130,027,165 | |
| -1 | -130,027,165 |
Let's try dividing by 4:
130,027,165 ÷ 4 = 32,506,791.25
If the quotient is a whole number, then 4 and 32,506,791.25 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 | 130,027,165 | |
| -1 | 130,027,165 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 23 | 95 | 115 | 437 | 2,185 | 59,509 | 297,545 | 1,130,671 | 1,368,707 | 5,653,355 | 6,843,535 | 26,005,433 | 130,027,165 |
| -1 | -5 | -19 | -23 | -95 | -115 | -437 | -2,185 | -59,509 | -297,545 | -1,130,671 | -1,368,707 | -5,653,355 | -6,843,535 | -26,005,433 | -130,027,165 |
