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 5,815,105, 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 | 5,815,105 | |
| -1 | -5,815,105 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,815,105.
Example:
1 x 5,815,105 = 5,815,105
and
-1 x -5,815,105 = 5,815,105
Notice both answers equal 5,815,105
With that explanation out of the way, let's continue. Next, we take the number 5,815,105 and divide it by 2:
5,815,105 ÷ 2 = 2,907,552.5
If the quotient is a whole number, then 2 and 2,907,552.5 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 | 5,815,105 | |
| -1 | -5,815,105 |
Now, we try dividing 5,815,105 by 3:
5,815,105 ÷ 3 = 1,938,368.3333
If the quotient is a whole number, then 3 and 1,938,368.3333 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 | 5,815,105 | |
| -1 | -5,815,105 |
Let's try dividing by 4:
5,815,105 ÷ 4 = 1,453,776.25
If the quotient is a whole number, then 4 and 1,453,776.25 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 | 5,815,105 | |
| -1 | 5,815,105 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 37 | 43 | 85 | 185 | 215 | 629 | 731 | 1,591 | 1,849 | 3,145 | 3,655 | 7,955 | 9,245 | 27,047 | 31,433 | 68,413 | 135,235 | 157,165 | 342,065 | 1,163,021 | 5,815,105 |
| -1 | -5 | -17 | -37 | -43 | -85 | -185 | -215 | -629 | -731 | -1,591 | -1,849 | -3,145 | -3,655 | -7,955 | -9,245 | -27,047 | -31,433 | -68,413 | -135,235 | -157,165 | -342,065 | -1,163,021 | -5,815,105 |
