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 130,424,203, 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 | 130,424,203 | |
| -1 | -130,424,203 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 130,424,203.
Example:
1 x 130,424,203 = 130,424,203
and
-1 x -130,424,203 = 130,424,203
Notice both answers equal 130,424,203
With that explanation out of the way, let's continue. Next, we take the number 130,424,203 and divide it by 2:
130,424,203 ÷ 2 = 65,212,101.5
If the quotient is a whole number, then 2 and 65,212,101.5 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 | 130,424,203 | |
| -1 | -130,424,203 |
Now, we try dividing 130,424,203 by 3:
130,424,203 ÷ 3 = 43,474,734.3333
If the quotient is a whole number, then 3 and 43,474,734.3333 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 | 130,424,203 | |
| -1 | -130,424,203 |
Let's try dividing by 4:
130,424,203 ÷ 4 = 32,606,050.75
If the quotient is a whole number, then 4 and 32,606,050.75 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 | 130,424,203 | |
| -1 | 130,424,203 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 43 | 91 | 301 | 559 | 3,913 | 33,331 | 233,317 | 433,303 | 1,433,233 | 3,033,121 | 10,032,631 | 18,632,029 | 130,424,203 |
| -1 | -7 | -13 | -43 | -91 | -301 | -559 | -3,913 | -33,331 | -233,317 | -433,303 | -1,433,233 | -3,033,121 | -10,032,631 | -18,632,029 | -130,424,203 |
