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 1,717,205, 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 | 1,717,205 | |
| -1 | -1,717,205 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,717,205.
Example:
1 x 1,717,205 = 1,717,205
and
-1 x -1,717,205 = 1,717,205
Notice both answers equal 1,717,205
With that explanation out of the way, let's continue. Next, we take the number 1,717,205 and divide it by 2:
1,717,205 ÷ 2 = 858,602.5
If the quotient is a whole number, then 2 and 858,602.5 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 | 1,717,205 | |
| -1 | -1,717,205 |
Now, we try dividing 1,717,205 by 3:
1,717,205 ÷ 3 = 572,401.6667
If the quotient is a whole number, then 3 and 572,401.6667 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 | 1,717,205 | |
| -1 | -1,717,205 |
Let's try dividing by 4:
1,717,205 ÷ 4 = 429,301.25
If the quotient is a whole number, then 4 and 429,301.25 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 | 1,717,205 | |
| -1 | 1,717,205 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 43 | 49 | 163 | 215 | 245 | 301 | 815 | 1,141 | 1,505 | 2,107 | 5,705 | 7,009 | 7,987 | 10,535 | 35,045 | 39,935 | 49,063 | 245,315 | 343,441 | 1,717,205 |
| -1 | -5 | -7 | -35 | -43 | -49 | -163 | -215 | -245 | -301 | -815 | -1,141 | -1,505 | -2,107 | -5,705 | -7,009 | -7,987 | -10,535 | -35,045 | -39,935 | -49,063 | -245,315 | -343,441 | -1,717,205 |
