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 17,741,717, 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 | 17,741,717 | |
| -1 | -17,741,717 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 17,741,717.
Example:
1 x 17,741,717 = 17,741,717
and
-1 x -17,741,717 = 17,741,717
Notice both answers equal 17,741,717
With that explanation out of the way, let's continue. Next, we take the number 17,741,717 and divide it by 2:
17,741,717 ÷ 2 = 8,870,858.5
If the quotient is a whole number, then 2 and 8,870,858.5 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 | 17,741,717 | |
| -1 | -17,741,717 |
Now, we try dividing 17,741,717 by 3:
17,741,717 ÷ 3 = 5,913,905.6667
If the quotient is a whole number, then 3 and 5,913,905.6667 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 | 17,741,717 | |
| -1 | -17,741,717 |
Let's try dividing by 4:
17,741,717 ÷ 4 = 4,435,429.25
If the quotient is a whole number, then 4 and 4,435,429.25 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 | 17,741,717 | |
| -1 | 17,741,717 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 161 | 263 | 419 | 1,841 | 2,933 | 6,049 | 9,637 | 42,343 | 67,459 | 110,197 | 771,379 | 2,534,531 | 17,741,717 |
| -1 | -7 | -23 | -161 | -263 | -419 | -1,841 | -2,933 | -6,049 | -9,637 | -42,343 | -67,459 | -110,197 | -771,379 | -2,534,531 | -17,741,717 |
