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 5,550,415, 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 | 5,550,415 | |
| -1 | -5,550,415 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,550,415.
Example:
1 x 5,550,415 = 5,550,415
and
-1 x -5,550,415 = 5,550,415
Notice both answers equal 5,550,415
With that explanation out of the way, let's continue. Next, we take the number 5,550,415 and divide it by 2:
5,550,415 ÷ 2 = 2,775,207.5
If the quotient is a whole number, then 2 and 2,775,207.5 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 | 5,550,415 | |
| -1 | -5,550,415 |
Now, we try dividing 5,550,415 by 3:
5,550,415 ÷ 3 = 1,850,138.3333
If the quotient is a whole number, then 3 and 1,850,138.3333 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 | 5,550,415 | |
| -1 | -5,550,415 |
Let's try dividing by 4:
5,550,415 ÷ 4 = 1,387,603.75
If the quotient is a whole number, then 4 and 1,387,603.75 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 | 5,550,415 | |
| -1 | 5,550,415 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 17 | 65 | 85 | 221 | 1,105 | 5,023 | 25,115 | 65,299 | 85,391 | 326,495 | 426,955 | 1,110,083 | 5,550,415 |
| -1 | -5 | -13 | -17 | -65 | -85 | -221 | -1,105 | -5,023 | -25,115 | -65,299 | -85,391 | -326,495 | -426,955 | -1,110,083 | -5,550,415 |
