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 130,034,021, 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 | 130,034,021 | |
| -1 | -130,034,021 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 130,034,021.
Example:
1 x 130,034,021 = 130,034,021
and
-1 x -130,034,021 = 130,034,021
Notice both answers equal 130,034,021
With that explanation out of the way, let's continue. Next, we take the number 130,034,021 and divide it by 2:
130,034,021 ÷ 2 = 65,017,010.5
If the quotient is a whole number, then 2 and 65,017,010.5 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 | 130,034,021 | |
| -1 | -130,034,021 |
Now, we try dividing 130,034,021 by 3:
130,034,021 ÷ 3 = 43,344,673.6667
If the quotient is a whole number, then 3 and 43,344,673.6667 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 | 130,034,021 | |
| -1 | -130,034,021 |
Let's try dividing by 4:
130,034,021 ÷ 4 = 32,508,505.25
If the quotient is a whole number, then 4 and 32,508,505.25 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 | 130,034,021 | |
| -1 | 130,034,021 |
If you did it right, you will end up with this table:
| 1 | 13 | 37 | 43 | 481 | 559 | 1,591 | 6,287 | 20,683 | 81,731 | 232,619 | 270,341 | 3,024,047 | 3,514,433 | 10,002,617 | 130,034,021 |
| -1 | -13 | -37 | -43 | -481 | -559 | -1,591 | -6,287 | -20,683 | -81,731 | -232,619 | -270,341 | -3,024,047 | -3,514,433 | -10,002,617 | -130,034,021 |
