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 17,073,287, 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 | 17,073,287 | |
| -1 | -17,073,287 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 17,073,287.
Example:
1 x 17,073,287 = 17,073,287
and
-1 x -17,073,287 = 17,073,287
Notice both answers equal 17,073,287
With that explanation out of the way, let's continue. Next, we take the number 17,073,287 and divide it by 2:
17,073,287 ÷ 2 = 8,536,643.5
If the quotient is a whole number, then 2 and 8,536,643.5 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 | 17,073,287 | |
| -1 | -17,073,287 |
Now, we try dividing 17,073,287 by 3:
17,073,287 ÷ 3 = 5,691,095.6667
If the quotient is a whole number, then 3 and 5,691,095.6667 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 | 17,073,287 | |
| -1 | -17,073,287 |
Let's try dividing by 4:
17,073,287 ÷ 4 = 4,268,321.75
If the quotient is a whole number, then 4 and 4,268,321.75 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 | 17,073,287 | |
| -1 | 17,073,287 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 17 | 77 | 119 | 187 | 1,309 | 13,043 | 91,301 | 143,473 | 221,731 | 1,004,311 | 1,552,117 | 2,439,041 | 17,073,287 |
| -1 | -7 | -11 | -17 | -77 | -119 | -187 | -1,309 | -13,043 | -91,301 | -143,473 | -221,731 | -1,004,311 | -1,552,117 | -2,439,041 | -17,073,287 |
