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 17,117,345, 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 | 17,117,345 | |
| -1 | -17,117,345 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 17,117,345.
Example:
1 x 17,117,345 = 17,117,345
and
-1 x -17,117,345 = 17,117,345
Notice both answers equal 17,117,345
With that explanation out of the way, let's continue. Next, we take the number 17,117,345 and divide it by 2:
17,117,345 ÷ 2 = 8,558,672.5
If the quotient is a whole number, then 2 and 8,558,672.5 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 | 17,117,345 | |
| -1 | -17,117,345 |
Now, we try dividing 17,117,345 by 3:
17,117,345 ÷ 3 = 5,705,781.6667
If the quotient is a whole number, then 3 and 5,705,781.6667 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 | 17,117,345 | |
| -1 | -17,117,345 |
Let's try dividing by 4:
17,117,345 ÷ 4 = 4,279,336.25
If the quotient is a whole number, then 4 and 4,279,336.25 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 | 17,117,345 | |
| -1 | 17,117,345 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 233 | 1,165 | 1,631 | 2,099 | 8,155 | 10,495 | 14,693 | 73,465 | 489,067 | 2,445,335 | 3,423,469 | 17,117,345 |
| -1 | -5 | -7 | -35 | -233 | -1,165 | -1,631 | -2,099 | -8,155 | -10,495 | -14,693 | -73,465 | -489,067 | -2,445,335 | -3,423,469 | -17,117,345 |
