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 17,342,897, 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 | 17,342,897 | |
| -1 | -17,342,897 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 17,342,897.
Example:
1 x 17,342,897 = 17,342,897
and
-1 x -17,342,897 = 17,342,897
Notice both answers equal 17,342,897
With that explanation out of the way, let's continue. Next, we take the number 17,342,897 and divide it by 2:
17,342,897 ÷ 2 = 8,671,448.5
If the quotient is a whole number, then 2 and 8,671,448.5 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 | 17,342,897 | |
| -1 | -17,342,897 |
Now, we try dividing 17,342,897 by 3:
17,342,897 ÷ 3 = 5,780,965.6667
If the quotient is a whole number, then 3 and 5,780,965.6667 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 | 17,342,897 | |
| -1 | -17,342,897 |
Let's try dividing by 4:
17,342,897 ÷ 4 = 4,335,724.25
If the quotient is a whole number, then 4 and 4,335,724.25 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 | 17,342,897 | |
| -1 | 17,342,897 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 23 | 143 | 253 | 299 | 3,289 | 5,273 | 58,003 | 68,549 | 121,279 | 754,039 | 1,334,069 | 1,576,627 | 17,342,897 |
| -1 | -11 | -13 | -23 | -143 | -253 | -299 | -3,289 | -5,273 | -58,003 | -68,549 | -121,279 | -754,039 | -1,334,069 | -1,576,627 | -17,342,897 |
