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 32,242,015, 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 | 32,242,015 | |
| -1 | -32,242,015 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 32,242,015.
Example:
1 x 32,242,015 = 32,242,015
and
-1 x -32,242,015 = 32,242,015
Notice both answers equal 32,242,015
With that explanation out of the way, let's continue. Next, we take the number 32,242,015 and divide it by 2:
32,242,015 ÷ 2 = 16,121,007.5
If the quotient is a whole number, then 2 and 16,121,007.5 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 | 32,242,015 | |
| -1 | -32,242,015 |
Now, we try dividing 32,242,015 by 3:
32,242,015 ÷ 3 = 10,747,338.3333
If the quotient is a whole number, then 3 and 10,747,338.3333 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 | 32,242,015 | |
| -1 | -32,242,015 |
Let's try dividing by 4:
32,242,015 ÷ 4 = 8,060,503.75
If the quotient is a whole number, then 4 and 8,060,503.75 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 | 32,242,015 | |
| -1 | 32,242,015 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 31 | 65 | 155 | 403 | 2,015 | 16,001 | 80,005 | 208,013 | 496,031 | 1,040,065 | 2,480,155 | 6,448,403 | 32,242,015 |
| -1 | -5 | -13 | -31 | -65 | -155 | -403 | -2,015 | -16,001 | -80,005 | -208,013 | -496,031 | -1,040,065 | -2,480,155 | -6,448,403 | -32,242,015 |
