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 1,001,585, 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 | 1,001,585 | |
| -1 | -1,001,585 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,001,585.
Example:
1 x 1,001,585 = 1,001,585
and
-1 x -1,001,585 = 1,001,585
Notice both answers equal 1,001,585
With that explanation out of the way, let's continue. Next, we take the number 1,001,585 and divide it by 2:
1,001,585 ÷ 2 = 500,792.5
If the quotient is a whole number, then 2 and 500,792.5 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 | 1,001,585 | |
| -1 | -1,001,585 |
Now, we try dividing 1,001,585 by 3:
1,001,585 ÷ 3 = 333,861.6667
If the quotient is a whole number, then 3 and 333,861.6667 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 | 1,001,585 | |
| -1 | -1,001,585 |
Let's try dividing by 4:
1,001,585 ÷ 4 = 250,396.25
If the quotient is a whole number, then 4 and 250,396.25 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 | 1,001,585 | |
| -1 | 1,001,585 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 19 | 65 | 95 | 247 | 811 | 1,235 | 4,055 | 10,543 | 15,409 | 52,715 | 77,045 | 200,317 | 1,001,585 |
| -1 | -5 | -13 | -19 | -65 | -95 | -247 | -811 | -1,235 | -4,055 | -10,543 | -15,409 | -52,715 | -77,045 | -200,317 | -1,001,585 |
