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 130,014,313, 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 | 130,014,313 | |
| -1 | -130,014,313 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 130,014,313.
Example:
1 x 130,014,313 = 130,014,313
and
-1 x -130,014,313 = 130,014,313
Notice both answers equal 130,014,313
With that explanation out of the way, let's continue. Next, we take the number 130,014,313 and divide it by 2:
130,014,313 ÷ 2 = 65,007,156.5
If the quotient is a whole number, then 2 and 65,007,156.5 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 | 130,014,313 | |
| -1 | -130,014,313 |
Now, we try dividing 130,014,313 by 3:
130,014,313 ÷ 3 = 43,338,104.3333
If the quotient is a whole number, then 3 and 43,338,104.3333 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 | 130,014,313 | |
| -1 | -130,014,313 |
Let's try dividing by 4:
130,014,313 ÷ 4 = 32,503,578.25
If the quotient is a whole number, then 4 and 32,503,578.25 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 | 130,014,313 | |
| -1 | 130,014,313 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 143 | 263 | 2,893 | 3,419 | 3,457 | 37,609 | 38,027 | 44,941 | 494,351 | 909,191 | 10,001,101 | 11,819,483 | 130,014,313 |
| -1 | -11 | -13 | -143 | -263 | -2,893 | -3,419 | -3,457 | -37,609 | -38,027 | -44,941 | -494,351 | -909,191 | -10,001,101 | -11,819,483 | -130,014,313 |
