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 5,550,281, 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 | 5,550,281 | |
| -1 | -5,550,281 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,550,281.
Example:
1 x 5,550,281 = 5,550,281
and
-1 x -5,550,281 = 5,550,281
Notice both answers equal 5,550,281
With that explanation out of the way, let's continue. Next, we take the number 5,550,281 and divide it by 2:
5,550,281 ÷ 2 = 2,775,140.5
If the quotient is a whole number, then 2 and 2,775,140.5 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 | 5,550,281 | |
| -1 | -5,550,281 |
Now, we try dividing 5,550,281 by 3:
5,550,281 ÷ 3 = 1,850,093.6667
If the quotient is a whole number, then 3 and 1,850,093.6667 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 | 5,550,281 | |
| -1 | -5,550,281 |
Let's try dividing by 4:
5,550,281 ÷ 4 = 1,387,570.25
If the quotient is a whole number, then 4 and 1,387,570.25 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 | 5,550,281 | |
| -1 | 5,550,281 |
If you did it right, you will end up with this table:
| 1 | 11 | 29 | 127 | 137 | 319 | 1,397 | 1,507 | 3,683 | 3,973 | 17,399 | 40,513 | 43,703 | 191,389 | 504,571 | 5,550,281 |
| -1 | -11 | -29 | -127 | -137 | -319 | -1,397 | -1,507 | -3,683 | -3,973 | -17,399 | -40,513 | -43,703 | -191,389 | -504,571 | -5,550,281 |
