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 130,045,135, 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 | 130,045,135 | |
| -1 | -130,045,135 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 130,045,135.
Example:
1 x 130,045,135 = 130,045,135
and
-1 x -130,045,135 = 130,045,135
Notice both answers equal 130,045,135
With that explanation out of the way, let's continue. Next, we take the number 130,045,135 and divide it by 2:
130,045,135 ÷ 2 = 65,022,567.5
If the quotient is a whole number, then 2 and 65,022,567.5 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 | 130,045,135 | |
| -1 | -130,045,135 |
Now, we try dividing 130,045,135 by 3:
130,045,135 ÷ 3 = 43,348,378.3333
If the quotient is a whole number, then 3 and 43,348,378.3333 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 | 130,045,135 | |
| -1 | -130,045,135 |
Let's try dividing by 4:
130,045,135 ÷ 4 = 32,511,283.75
If the quotient is a whole number, then 4 and 32,511,283.75 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 | 130,045,135 | |
| -1 | 130,045,135 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 29 | 55 | 145 | 319 | 1,595 | 81,533 | 407,665 | 896,863 | 2,364,457 | 4,484,315 | 11,822,285 | 26,009,027 | 130,045,135 |
| -1 | -5 | -11 | -29 | -55 | -145 | -319 | -1,595 | -81,533 | -407,665 | -896,863 | -2,364,457 | -4,484,315 | -11,822,285 | -26,009,027 | -130,045,135 |
