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 10,555,055, 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 | 10,555,055 | |
| -1 | -10,555,055 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,555,055.
Example:
1 x 10,555,055 = 10,555,055
and
-1 x -10,555,055 = 10,555,055
Notice both answers equal 10,555,055
With that explanation out of the way, let's continue. Next, we take the number 10,555,055 and divide it by 2:
10,555,055 ÷ 2 = 5,277,527.5
If the quotient is a whole number, then 2 and 5,277,527.5 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 | 10,555,055 | |
| -1 | -10,555,055 |
Now, we try dividing 10,555,055 by 3:
10,555,055 ÷ 3 = 3,518,351.6667
If the quotient is a whole number, then 3 and 3,518,351.6667 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 | 10,555,055 | |
| -1 | -10,555,055 |
Let's try dividing by 4:
10,555,055 ÷ 4 = 2,638,763.75
If the quotient is a whole number, then 4 and 2,638,763.75 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 | 10,555,055 | |
| -1 | 10,555,055 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 97 | 485 | 679 | 3,109 | 3,395 | 15,545 | 21,763 | 108,815 | 301,573 | 1,507,865 | 2,111,011 | 10,555,055 |
| -1 | -5 | -7 | -35 | -97 | -485 | -679 | -3,109 | -3,395 | -15,545 | -21,763 | -108,815 | -301,573 | -1,507,865 | -2,111,011 | -10,555,055 |
