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 1,361,105, 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 | 1,361,105 | |
| -1 | -1,361,105 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,361,105.
Example:
1 x 1,361,105 = 1,361,105
and
-1 x -1,361,105 = 1,361,105
Notice both answers equal 1,361,105
With that explanation out of the way, let's continue. Next, we take the number 1,361,105 and divide it by 2:
1,361,105 ÷ 2 = 680,552.5
If the quotient is a whole number, then 2 and 680,552.5 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 | 1,361,105 | |
| -1 | -1,361,105 |
Now, we try dividing 1,361,105 by 3:
1,361,105 ÷ 3 = 453,701.6667
If the quotient is a whole number, then 3 and 453,701.6667 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 | 1,361,105 | |
| -1 | -1,361,105 |
Let's try dividing by 4:
1,361,105 ÷ 4 = 340,276.25
If the quotient is a whole number, then 4 and 340,276.25 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 | 1,361,105 | |
| -1 | 1,361,105 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 67 | 85 | 239 | 335 | 1,139 | 1,195 | 4,063 | 5,695 | 16,013 | 20,315 | 80,065 | 272,221 | 1,361,105 |
| -1 | -5 | -17 | -67 | -85 | -239 | -335 | -1,139 | -1,195 | -4,063 | -5,695 | -16,013 | -20,315 | -80,065 | -272,221 | -1,361,105 |
