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 15,065,105, 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 | 15,065,105 | |
| -1 | -15,065,105 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 15,065,105.
Example:
1 x 15,065,105 = 15,065,105
and
-1 x -15,065,105 = 15,065,105
Notice both answers equal 15,065,105
With that explanation out of the way, let's continue. Next, we take the number 15,065,105 and divide it by 2:
15,065,105 ÷ 2 = 7,532,552.5
If the quotient is a whole number, then 2 and 7,532,552.5 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 | 15,065,105 | |
| -1 | -15,065,105 |
Now, we try dividing 15,065,105 by 3:
15,065,105 ÷ 3 = 5,021,701.6667
If the quotient is a whole number, then 3 and 5,021,701.6667 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 | 15,065,105 | |
| -1 | -15,065,105 |
Let's try dividing by 4:
15,065,105 ÷ 4 = 3,766,276.25
If the quotient is a whole number, then 4 and 3,766,276.25 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 | 15,065,105 | |
| -1 | 15,065,105 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 37 | 55 | 121 | 185 | 407 | 605 | 673 | 2,035 | 3,365 | 4,477 | 7,403 | 22,385 | 24,901 | 37,015 | 81,433 | 124,505 | 273,911 | 407,165 | 1,369,555 | 3,013,021 | 15,065,105 |
| -1 | -5 | -11 | -37 | -55 | -121 | -185 | -407 | -605 | -673 | -2,035 | -3,365 | -4,477 | -7,403 | -22,385 | -24,901 | -37,015 | -81,433 | -124,505 | -273,911 | -407,165 | -1,369,555 | -3,013,021 | -15,065,105 |
