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 17,405,531, 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 | 17,405,531 | |
| -1 | -17,405,531 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 17,405,531.
Example:
1 x 17,405,531 = 17,405,531
and
-1 x -17,405,531 = 17,405,531
Notice both answers equal 17,405,531
With that explanation out of the way, let's continue. Next, we take the number 17,405,531 and divide it by 2:
17,405,531 ÷ 2 = 8,702,765.5
If the quotient is a whole number, then 2 and 8,702,765.5 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 | 17,405,531 | |
| -1 | -17,405,531 |
Now, we try dividing 17,405,531 by 3:
17,405,531 ÷ 3 = 5,801,843.6667
If the quotient is a whole number, then 3 and 5,801,843.6667 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 | 17,405,531 | |
| -1 | -17,405,531 |
Let's try dividing by 4:
17,405,531 ÷ 4 = 4,351,382.75
If the quotient is a whole number, then 4 and 4,351,382.75 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 | 17,405,531 | |
| -1 | 17,405,531 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 59 | 143 | 649 | 767 | 2,063 | 8,437 | 22,693 | 26,819 | 121,717 | 295,009 | 1,338,887 | 1,582,321 | 17,405,531 |
| -1 | -11 | -13 | -59 | -143 | -649 | -767 | -2,063 | -8,437 | -22,693 | -26,819 | -121,717 | -295,009 | -1,338,887 | -1,582,321 | -17,405,531 |
