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 130,043,419, 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 | 130,043,419 | |
| -1 | -130,043,419 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 130,043,419.
Example:
1 x 130,043,419 = 130,043,419
and
-1 x -130,043,419 = 130,043,419
Notice both answers equal 130,043,419
With that explanation out of the way, let's continue. Next, we take the number 130,043,419 and divide it by 2:
130,043,419 ÷ 2 = 65,021,709.5
If the quotient is a whole number, then 2 and 65,021,709.5 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 | 130,043,419 | |
| -1 | -130,043,419 |
Now, we try dividing 130,043,419 by 3:
130,043,419 ÷ 3 = 43,347,806.3333
If the quotient is a whole number, then 3 and 43,347,806.3333 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 | 130,043,419 | |
| -1 | -130,043,419 |
Let's try dividing by 4:
130,043,419 ÷ 4 = 32,510,854.75
If the quotient is a whole number, then 4 and 32,510,854.75 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 | 130,043,419 | |
| -1 | 130,043,419 |
If you did it right, you will end up with this table:
| 1 | 11 | 31 | 37 | 121 | 341 | 407 | 937 | 1,147 | 3,751 | 4,477 | 10,307 | 12,617 | 29,047 | 34,669 | 113,377 | 138,787 | 319,517 | 381,359 | 1,074,739 | 3,514,687 | 4,194,949 | 11,822,129 | 130,043,419 |
| -1 | -11 | -31 | -37 | -121 | -341 | -407 | -937 | -1,147 | -3,751 | -4,477 | -10,307 | -12,617 | -29,047 | -34,669 | -113,377 | -138,787 | -319,517 | -381,359 | -1,074,739 | -3,514,687 | -4,194,949 | -11,822,129 | -130,043,419 |
