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 32,131,099, 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 | 32,131,099 | |
| -1 | -32,131,099 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 32,131,099.
Example:
1 x 32,131,099 = 32,131,099
and
-1 x -32,131,099 = 32,131,099
Notice both answers equal 32,131,099
With that explanation out of the way, let's continue. Next, we take the number 32,131,099 and divide it by 2:
32,131,099 ÷ 2 = 16,065,549.5
If the quotient is a whole number, then 2 and 16,065,549.5 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 | 32,131,099 | |
| -1 | -32,131,099 |
Now, we try dividing 32,131,099 by 3:
32,131,099 ÷ 3 = 10,710,366.3333
If the quotient is a whole number, then 3 and 10,710,366.3333 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 | 32,131,099 | |
| -1 | -32,131,099 |
Let's try dividing by 4:
32,131,099 ÷ 4 = 8,032,774.75
If the quotient is a whole number, then 4 and 8,032,774.75 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 | 32,131,099 | |
| -1 | 32,131,099 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 13 | 77 | 91 | 143 | 1,001 | 32,099 | 224,693 | 353,089 | 417,287 | 2,471,623 | 2,921,009 | 4,590,157 | 32,131,099 |
| -1 | -7 | -11 | -13 | -77 | -91 | -143 | -1,001 | -32,099 | -224,693 | -353,089 | -417,287 | -2,471,623 | -2,921,009 | -4,590,157 | -32,131,099 |
