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 32,033,015, 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 | 32,033,015 | |
| -1 | -32,033,015 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 32,033,015.
Example:
1 x 32,033,015 = 32,033,015
and
-1 x -32,033,015 = 32,033,015
Notice both answers equal 32,033,015
With that explanation out of the way, let's continue. Next, we take the number 32,033,015 and divide it by 2:
32,033,015 ÷ 2 = 16,016,507.5
If the quotient is a whole number, then 2 and 16,016,507.5 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 | 32,033,015 | |
| -1 | -32,033,015 |
Now, we try dividing 32,033,015 by 3:
32,033,015 ÷ 3 = 10,677,671.6667
If the quotient is a whole number, then 3 and 10,677,671.6667 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 | 32,033,015 | |
| -1 | -32,033,015 |
Let's try dividing by 4:
32,033,015 ÷ 4 = 8,008,253.75
If the quotient is a whole number, then 4 and 8,008,253.75 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 | 32,033,015 | |
| -1 | 32,033,015 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 17 | 35 | 49 | 85 | 119 | 245 | 595 | 833 | 4,165 | 7,691 | 38,455 | 53,837 | 130,747 | 269,185 | 376,859 | 653,735 | 915,229 | 1,884,295 | 4,576,145 | 6,406,603 | 32,033,015 |
| -1 | -5 | -7 | -17 | -35 | -49 | -85 | -119 | -245 | -595 | -833 | -4,165 | -7,691 | -38,455 | -53,837 | -130,747 | -269,185 | -376,859 | -653,735 | -915,229 | -1,884,295 | -4,576,145 | -6,406,603 | -32,033,015 |
