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 32,030,219, 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 | 32,030,219 | |
| -1 | -32,030,219 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 32,030,219.
Example:
1 x 32,030,219 = 32,030,219
and
-1 x -32,030,219 = 32,030,219
Notice both answers equal 32,030,219
With that explanation out of the way, let's continue. Next, we take the number 32,030,219 and divide it by 2:
32,030,219 ÷ 2 = 16,015,109.5
If the quotient is a whole number, then 2 and 16,015,109.5 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 | 32,030,219 | |
| -1 | -32,030,219 |
Now, we try dividing 32,030,219 by 3:
32,030,219 ÷ 3 = 10,676,739.6667
If the quotient is a whole number, then 3 and 10,676,739.6667 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 | 32,030,219 | |
| -1 | -32,030,219 |
Let's try dividing by 4:
32,030,219 ÷ 4 = 8,007,554.75
If the quotient is a whole number, then 4 and 8,007,554.75 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 | 32,030,219 | |
| -1 | 32,030,219 |
If you did it right, you will end up with this table:
| 1 | 13 | 19 | 103 | 247 | 1,259 | 1,339 | 1,957 | 16,367 | 23,921 | 25,441 | 129,677 | 310,973 | 1,685,801 | 2,463,863 | 32,030,219 |
| -1 | -13 | -19 | -103 | -247 | -1,259 | -1,339 | -1,957 | -16,367 | -23,921 | -25,441 | -129,677 | -310,973 | -1,685,801 | -2,463,863 | -32,030,219 |
