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 131,000,203, 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 | 131,000,203 | |
| -1 | -131,000,203 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 131,000,203.
Example:
1 x 131,000,203 = 131,000,203
and
-1 x -131,000,203 = 131,000,203
Notice both answers equal 131,000,203
With that explanation out of the way, let's continue. Next, we take the number 131,000,203 and divide it by 2:
131,000,203 ÷ 2 = 65,500,101.5
If the quotient is a whole number, then 2 and 65,500,101.5 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 | 131,000,203 | |
| -1 | -131,000,203 |
Now, we try dividing 131,000,203 by 3:
131,000,203 ÷ 3 = 43,666,734.3333
If the quotient is a whole number, then 3 and 43,666,734.3333 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 | 131,000,203 | |
| -1 | -131,000,203 |
Let's try dividing by 4:
131,000,203 ÷ 4 = 32,750,050.75
If the quotient is a whole number, then 4 and 32,750,050.75 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 | 131,000,203 | |
| -1 | 131,000,203 |
If you did it right, you will end up with this table:
| 1 | 23 | 31 | 313 | 587 | 713 | 7,199 | 9,703 | 13,501 | 18,197 | 183,731 | 223,169 | 418,531 | 4,225,813 | 5,695,661 | 131,000,203 |
| -1 | -23 | -31 | -313 | -587 | -713 | -7,199 | -9,703 | -13,501 | -18,197 | -183,731 | -223,169 | -418,531 | -4,225,813 | -5,695,661 | -131,000,203 |
