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 5,515,307, 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 | 5,515,307 | |
| -1 | -5,515,307 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,515,307.
Example:
1 x 5,515,307 = 5,515,307
and
-1 x -5,515,307 = 5,515,307
Notice both answers equal 5,515,307
With that explanation out of the way, let's continue. Next, we take the number 5,515,307 and divide it by 2:
5,515,307 ÷ 2 = 2,757,653.5
If the quotient is a whole number, then 2 and 2,757,653.5 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 | 5,515,307 | |
| -1 | -5,515,307 |
Now, we try dividing 5,515,307 by 3:
5,515,307 ÷ 3 = 1,838,435.6667
If the quotient is a whole number, then 3 and 1,838,435.6667 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 | 5,515,307 | |
| -1 | -5,515,307 |
Let's try dividing by 4:
5,515,307 ÷ 4 = 1,378,826.75
If the quotient is a whole number, then 4 and 1,378,826.75 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 | 5,515,307 | |
| -1 | 5,515,307 |
If you did it right, you will end up with this table:
| 1 | 7 | 29 | 101 | 203 | 269 | 707 | 1,883 | 2,929 | 7,801 | 20,503 | 27,169 | 54,607 | 190,183 | 787,901 | 5,515,307 |
| -1 | -7 | -29 | -101 | -203 | -269 | -707 | -1,883 | -2,929 | -7,801 | -20,503 | -27,169 | -54,607 | -190,183 | -787,901 | -5,515,307 |
