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 413,015, 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 | 413,015 | |
| -1 | -413,015 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 413,015.
Example:
1 x 413,015 = 413,015
and
-1 x -413,015 = 413,015
Notice both answers equal 413,015
With that explanation out of the way, let's continue. Next, we take the number 413,015 and divide it by 2:
413,015 ÷ 2 = 206,507.5
If the quotient is a whole number, then 2 and 206,507.5 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 | 413,015 | |
| -1 | -413,015 |
Now, we try dividing 413,015 by 3:
413,015 ÷ 3 = 137,671.6667
If the quotient is a whole number, then 3 and 137,671.6667 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 | 413,015 | |
| -1 | -413,015 |
Let's try dividing by 4:
413,015 ÷ 4 = 103,253.75
If the quotient is a whole number, then 4 and 103,253.75 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 | 413,015 | |
| -1 | 413,015 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 43 | 85 | 113 | 215 | 565 | 731 | 1,921 | 3,655 | 4,859 | 9,605 | 24,295 | 82,603 | 413,015 |
| -1 | -5 | -17 | -43 | -85 | -113 | -215 | -565 | -731 | -1,921 | -3,655 | -4,859 | -9,605 | -24,295 | -82,603 | -413,015 |
