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 55,555,205, 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 | 55,555,205 | |
| -1 | -55,555,205 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 55,555,205.
Example:
1 x 55,555,205 = 55,555,205
and
-1 x -55,555,205 = 55,555,205
Notice both answers equal 55,555,205
With that explanation out of the way, let's continue. Next, we take the number 55,555,205 and divide it by 2:
55,555,205 ÷ 2 = 27,777,602.5
If the quotient is a whole number, then 2 and 27,777,602.5 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 | 55,555,205 | |
| -1 | -55,555,205 |
Now, we try dividing 55,555,205 by 3:
55,555,205 ÷ 3 = 18,518,401.6667
If the quotient is a whole number, then 3 and 18,518,401.6667 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 | 55,555,205 | |
| -1 | -55,555,205 |
Let's try dividing by 4:
55,555,205 ÷ 4 = 13,888,801.25
If the quotient is a whole number, then 4 and 13,888,801.25 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 | 55,555,205 | |
| -1 | 55,555,205 |
If you did it right, you will end up with this table:
| 1 | 5 | 41 | 205 | 457 | 593 | 2,285 | 2,965 | 18,737 | 24,313 | 93,685 | 121,565 | 271,001 | 1,355,005 | 11,111,041 | 55,555,205 |
| -1 | -5 | -41 | -205 | -457 | -593 | -2,285 | -2,965 | -18,737 | -24,313 | -93,685 | -121,565 | -271,001 | -1,355,005 | -11,111,041 | -55,555,205 |
