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 1,090,115, 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 | 1,090,115 | |
| -1 | -1,090,115 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,090,115.
Example:
1 x 1,090,115 = 1,090,115
and
-1 x -1,090,115 = 1,090,115
Notice both answers equal 1,090,115
With that explanation out of the way, let's continue. Next, we take the number 1,090,115 and divide it by 2:
1,090,115 ÷ 2 = 545,057.5
If the quotient is a whole number, then 2 and 545,057.5 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 | 1,090,115 | |
| -1 | -1,090,115 |
Now, we try dividing 1,090,115 by 3:
1,090,115 ÷ 3 = 363,371.6667
If the quotient is a whole number, then 3 and 363,371.6667 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 | 1,090,115 | |
| -1 | -1,090,115 |
Let's try dividing by 4:
1,090,115 ÷ 4 = 272,528.75
If the quotient is a whole number, then 4 and 272,528.75 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 | 1,090,115 | |
| -1 | 1,090,115 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 31 | 65 | 155 | 403 | 541 | 2,015 | 2,705 | 7,033 | 16,771 | 35,165 | 83,855 | 218,023 | 1,090,115 |
| -1 | -5 | -13 | -31 | -65 | -155 | -403 | -541 | -2,015 | -2,705 | -7,033 | -16,771 | -35,165 | -83,855 | -218,023 | -1,090,115 |
