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 131,433,103, 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 | 131,433,103 | |
| -1 | -131,433,103 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 131,433,103.
Example:
1 x 131,433,103 = 131,433,103
and
-1 x -131,433,103 = 131,433,103
Notice both answers equal 131,433,103
With that explanation out of the way, let's continue. Next, we take the number 131,433,103 and divide it by 2:
131,433,103 ÷ 2 = 65,716,551.5
If the quotient is a whole number, then 2 and 65,716,551.5 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 | 131,433,103 | |
| -1 | -131,433,103 |
Now, we try dividing 131,433,103 by 3:
131,433,103 ÷ 3 = 43,811,034.3333
If the quotient is a whole number, then 3 and 43,811,034.3333 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 | 131,433,103 | |
| -1 | -131,433,103 |
Let's try dividing by 4:
131,433,103 ÷ 4 = 32,858,275.75
If the quotient is a whole number, then 4 and 32,858,275.75 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 | 131,433,103 | |
| -1 | 131,433,103 |
If you did it right, you will end up with this table:
| 1 | 17 | 47 | 271 | 607 | 799 | 4,607 | 10,319 | 12,737 | 28,529 | 164,497 | 216,529 | 484,993 | 2,796,449 | 7,731,359 | 131,433,103 |
| -1 | -17 | -47 | -271 | -607 | -799 | -4,607 | -10,319 | -12,737 | -28,529 | -164,497 | -216,529 | -484,993 | -2,796,449 | -7,731,359 | -131,433,103 |
