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 130,146,203, 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 | 130,146,203 | |
| -1 | -130,146,203 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 130,146,203.
Example:
1 x 130,146,203 = 130,146,203
and
-1 x -130,146,203 = 130,146,203
Notice both answers equal 130,146,203
With that explanation out of the way, let's continue. Next, we take the number 130,146,203 and divide it by 2:
130,146,203 ÷ 2 = 65,073,101.5
If the quotient is a whole number, then 2 and 65,073,101.5 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 | 130,146,203 | |
| -1 | -130,146,203 |
Now, we try dividing 130,146,203 by 3:
130,146,203 ÷ 3 = 43,382,067.6667
If the quotient is a whole number, then 3 and 43,382,067.6667 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 | 130,146,203 | |
| -1 | -130,146,203 |
Let's try dividing by 4:
130,146,203 ÷ 4 = 32,536,550.75
If the quotient is a whole number, then 4 and 32,536,550.75 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 | 130,146,203 | |
| -1 | 130,146,203 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 187 | 307 | 2,267 | 3,377 | 5,219 | 24,937 | 38,539 | 57,409 | 423,929 | 695,969 | 7,655,659 | 11,831,473 | 130,146,203 |
| -1 | -11 | -17 | -187 | -307 | -2,267 | -3,377 | -5,219 | -24,937 | -38,539 | -57,409 | -423,929 | -695,969 | -7,655,659 | -11,831,473 | -130,146,203 |
