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 130,304,083, 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 | 130,304,083 | |
| -1 | -130,304,083 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 130,304,083.
Example:
1 x 130,304,083 = 130,304,083
and
-1 x -130,304,083 = 130,304,083
Notice both answers equal 130,304,083
With that explanation out of the way, let's continue. Next, we take the number 130,304,083 and divide it by 2:
130,304,083 ÷ 2 = 65,152,041.5
If the quotient is a whole number, then 2 and 65,152,041.5 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 | 130,304,083 | |
| -1 | -130,304,083 |
Now, we try dividing 130,304,083 by 3:
130,304,083 ÷ 3 = 43,434,694.3333
If the quotient is a whole number, then 3 and 43,434,694.3333 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 | 130,304,083 | |
| -1 | -130,304,083 |
Let's try dividing by 4:
130,304,083 ÷ 4 = 32,576,020.75
If the quotient is a whole number, then 4 and 32,576,020.75 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 | 130,304,083 | |
| -1 | 130,304,083 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 49 | 91 | 337 | 607 | 637 | 2,359 | 4,249 | 4,381 | 7,891 | 16,513 | 29,743 | 30,667 | 55,237 | 204,559 | 214,669 | 386,659 | 1,431,913 | 2,659,267 | 10,023,391 | 18,614,869 | 130,304,083 |
| -1 | -7 | -13 | -49 | -91 | -337 | -607 | -637 | -2,359 | -4,249 | -4,381 | -7,891 | -16,513 | -29,743 | -30,667 | -55,237 | -204,559 | -214,669 | -386,659 | -1,431,913 | -2,659,267 | -10,023,391 | -18,614,869 | -130,304,083 |
