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 1,711,385, 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 | 1,711,385 | |
| -1 | -1,711,385 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,711,385.
Example:
1 x 1,711,385 = 1,711,385
and
-1 x -1,711,385 = 1,711,385
Notice both answers equal 1,711,385
With that explanation out of the way, let's continue. Next, we take the number 1,711,385 and divide it by 2:
1,711,385 ÷ 2 = 855,692.5
If the quotient is a whole number, then 2 and 855,692.5 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 | 1,711,385 | |
| -1 | -1,711,385 |
Now, we try dividing 1,711,385 by 3:
1,711,385 ÷ 3 = 570,461.6667
If the quotient is a whole number, then 3 and 570,461.6667 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 | 1,711,385 | |
| -1 | -1,711,385 |
Let's try dividing by 4:
1,711,385 ÷ 4 = 427,846.25
If the quotient is a whole number, then 4 and 427,846.25 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 | 1,711,385 | |
| -1 | 1,711,385 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 113 | 233 | 565 | 1,165 | 1,469 | 3,029 | 7,345 | 15,145 | 26,329 | 131,645 | 342,277 | 1,711,385 |
| -1 | -5 | -13 | -65 | -113 | -233 | -565 | -1,165 | -1,469 | -3,029 | -7,345 | -15,145 | -26,329 | -131,645 | -342,277 | -1,711,385 |
