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 17,540,405, 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 | 17,540,405 | |
| -1 | -17,540,405 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 17,540,405.
Example:
1 x 17,540,405 = 17,540,405
and
-1 x -17,540,405 = 17,540,405
Notice both answers equal 17,540,405
With that explanation out of the way, let's continue. Next, we take the number 17,540,405 and divide it by 2:
17,540,405 ÷ 2 = 8,770,202.5
If the quotient is a whole number, then 2 and 8,770,202.5 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 | 17,540,405 | |
| -1 | -17,540,405 |
Now, we try dividing 17,540,405 by 3:
17,540,405 ÷ 3 = 5,846,801.6667
If the quotient is a whole number, then 3 and 5,846,801.6667 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 | 17,540,405 | |
| -1 | -17,540,405 |
Let's try dividing by 4:
17,540,405 ÷ 4 = 4,385,101.25
If the quotient is a whole number, then 4 and 4,385,101.25 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 | 17,540,405 | |
| -1 | 17,540,405 |
If you did it right, you will end up with this table:
| 1 | 5 | 37 | 59 | 185 | 295 | 1,607 | 2,183 | 8,035 | 10,915 | 59,459 | 94,813 | 297,295 | 474,065 | 3,508,081 | 17,540,405 |
| -1 | -5 | -37 | -59 | -185 | -295 | -1,607 | -2,183 | -8,035 | -10,915 | -59,459 | -94,813 | -297,295 | -474,065 | -3,508,081 | -17,540,405 |
