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 32,881,609, 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 | 32,881,609 | |
| -1 | -32,881,609 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 32,881,609.
Example:
1 x 32,881,609 = 32,881,609
and
-1 x -32,881,609 = 32,881,609
Notice both answers equal 32,881,609
With that explanation out of the way, let's continue. Next, we take the number 32,881,609 and divide it by 2:
32,881,609 ÷ 2 = 16,440,804.5
If the quotient is a whole number, then 2 and 16,440,804.5 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 | 32,881,609 | |
| -1 | -32,881,609 |
Now, we try dividing 32,881,609 by 3:
32,881,609 ÷ 3 = 10,960,536.3333
If the quotient is a whole number, then 3 and 10,960,536.3333 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 | 32,881,609 | |
| -1 | -32,881,609 |
Let's try dividing by 4:
32,881,609 ÷ 4 = 8,220,402.25
If the quotient is a whole number, then 4 and 8,220,402.25 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 | 32,881,609 | |
| -1 | 32,881,609 |
If you did it right, you will end up with this table:
| 1 | 19 | 73 | 151 | 157 | 1,387 | 2,869 | 2,983 | 11,023 | 11,461 | 23,707 | 209,437 | 217,759 | 450,433 | 1,730,611 | 32,881,609 |
| -1 | -19 | -73 | -151 | -157 | -1,387 | -2,869 | -2,983 | -11,023 | -11,461 | -23,707 | -209,437 | -217,759 | -450,433 | -1,730,611 | -32,881,609 |
