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 17,344,505, 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 | 17,344,505 | |
| -1 | -17,344,505 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 17,344,505.
Example:
1 x 17,344,505 = 17,344,505
and
-1 x -17,344,505 = 17,344,505
Notice both answers equal 17,344,505
With that explanation out of the way, let's continue. Next, we take the number 17,344,505 and divide it by 2:
17,344,505 ÷ 2 = 8,672,252.5
If the quotient is a whole number, then 2 and 8,672,252.5 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 | 17,344,505 | |
| -1 | -17,344,505 |
Now, we try dividing 17,344,505 by 3:
17,344,505 ÷ 3 = 5,781,501.6667
If the quotient is a whole number, then 3 and 5,781,501.6667 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 | 17,344,505 | |
| -1 | -17,344,505 |
Let's try dividing by 4:
17,344,505 ÷ 4 = 4,336,126.25
If the quotient is a whole number, then 4 and 4,336,126.25 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 | 17,344,505 | |
| -1 | 17,344,505 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 419 | 487 | 2,095 | 2,435 | 7,123 | 8,279 | 35,615 | 41,395 | 204,053 | 1,020,265 | 3,468,901 | 17,344,505 |
| -1 | -5 | -17 | -85 | -419 | -487 | -2,095 | -2,435 | -7,123 | -8,279 | -35,615 | -41,395 | -204,053 | -1,020,265 | -3,468,901 | -17,344,505 |
