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 5,611,105, 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 | 5,611,105 | |
| -1 | -5,611,105 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,611,105.
Example:
1 x 5,611,105 = 5,611,105
and
-1 x -5,611,105 = 5,611,105
Notice both answers equal 5,611,105
With that explanation out of the way, let's continue. Next, we take the number 5,611,105 and divide it by 2:
5,611,105 ÷ 2 = 2,805,552.5
If the quotient is a whole number, then 2 and 2,805,552.5 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 | 5,611,105 | |
| -1 | -5,611,105 |
Now, we try dividing 5,611,105 by 3:
5,611,105 ÷ 3 = 1,870,368.3333
If the quotient is a whole number, then 3 and 1,870,368.3333 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 | 5,611,105 | |
| -1 | -5,611,105 |
Let's try dividing by 4:
5,611,105 ÷ 4 = 1,402,776.25
If the quotient is a whole number, then 4 and 1,402,776.25 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 | 5,611,105 | |
| -1 | 5,611,105 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 251 | 263 | 1,255 | 1,315 | 4,267 | 4,471 | 21,335 | 22,355 | 66,013 | 330,065 | 1,122,221 | 5,611,105 |
| -1 | -5 | -17 | -85 | -251 | -263 | -1,255 | -1,315 | -4,267 | -4,471 | -21,335 | -22,355 | -66,013 | -330,065 | -1,122,221 | -5,611,105 |
