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 55,055, 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 | 55,055 | |
| -1 | -55,055 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 55,055.
Example:
1 x 55,055 = 55,055
and
-1 x -55,055 = 55,055
Notice both answers equal 55,055
With that explanation out of the way, let's continue. Next, we take the number 55,055 and divide it by 2:
55,055 ÷ 2 = 27,527.5
If the quotient is a whole number, then 2 and 27,527.5 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 | 55,055 | |
| -1 | -55,055 |
Now, we try dividing 55,055 by 3:
55,055 ÷ 3 = 18,351.6667
If the quotient is a whole number, then 3 and 18,351.6667 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 | 55,055 | |
| -1 | -55,055 |
Let's try dividing by 4:
55,055 ÷ 4 = 13,763.75
If the quotient is a whole number, then 4 and 13,763.75 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 | 55,055 | |
| -1 | 55,055 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 11 | 13 | 35 | 55 | 65 | 77 | 91 | 121 | 143 | 385 | 455 | 605 | 715 | 847 | 1,001 | 1,573 | 4,235 | 5,005 | 7,865 | 11,011 | 55,055 |
| -1 | -5 | -7 | -11 | -13 | -35 | -55 | -65 | -77 | -91 | -121 | -143 | -385 | -455 | -605 | -715 | -847 | -1,001 | -1,573 | -4,235 | -5,005 | -7,865 | -11,011 | -55,055 |
