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 4,407,205, 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 | 4,407,205 | |
| -1 | -4,407,205 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,407,205.
Example:
1 x 4,407,205 = 4,407,205
and
-1 x -4,407,205 = 4,407,205
Notice both answers equal 4,407,205
With that explanation out of the way, let's continue. Next, we take the number 4,407,205 and divide it by 2:
4,407,205 ÷ 2 = 2,203,602.5
If the quotient is a whole number, then 2 and 2,203,602.5 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 | 4,407,205 | |
| -1 | -4,407,205 |
Now, we try dividing 4,407,205 by 3:
4,407,205 ÷ 3 = 1,469,068.3333
If the quotient is a whole number, then 3 and 1,469,068.3333 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 | 4,407,205 | |
| -1 | -4,407,205 |
Let's try dividing by 4:
4,407,205 ÷ 4 = 1,101,801.25
If the quotient is a whole number, then 4 and 1,101,801.25 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 | 4,407,205 | |
| -1 | 4,407,205 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 227 | 353 | 1,135 | 1,765 | 2,497 | 3,883 | 12,485 | 19,415 | 80,131 | 400,655 | 881,441 | 4,407,205 |
| -1 | -5 | -11 | -55 | -227 | -353 | -1,135 | -1,765 | -2,497 | -3,883 | -12,485 | -19,415 | -80,131 | -400,655 | -881,441 | -4,407,205 |
