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 4,405,511, 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 | 4,405,511 | |
| -1 | -4,405,511 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,405,511.
Example:
1 x 4,405,511 = 4,405,511
and
-1 x -4,405,511 = 4,405,511
Notice both answers equal 4,405,511
With that explanation out of the way, let's continue. Next, we take the number 4,405,511 and divide it by 2:
4,405,511 ÷ 2 = 2,202,755.5
If the quotient is a whole number, then 2 and 2,202,755.5 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 | 4,405,511 | |
| -1 | -4,405,511 |
Now, we try dividing 4,405,511 by 3:
4,405,511 ÷ 3 = 1,468,503.6667
If the quotient is a whole number, then 3 and 1,468,503.6667 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 | 4,405,511 | |
| -1 | -4,405,511 |
Let's try dividing by 4:
4,405,511 ÷ 4 = 1,101,377.75
If the quotient is a whole number, then 4 and 1,101,377.75 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 | 4,405,511 | |
| -1 | 4,405,511 |
If you did it right, you will end up with this table:
| 1 | 11 | 19 | 107 | 197 | 209 | 1,177 | 2,033 | 2,167 | 3,743 | 21,079 | 22,363 | 41,173 | 231,869 | 400,501 | 4,405,511 |
| -1 | -11 | -19 | -107 | -197 | -209 | -1,177 | -2,033 | -2,167 | -3,743 | -21,079 | -22,363 | -41,173 | -231,869 | -400,501 | -4,405,511 |
