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 17,138,285, 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 | 17,138,285 | |
| -1 | -17,138,285 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 17,138,285.
Example:
1 x 17,138,285 = 17,138,285
and
-1 x -17,138,285 = 17,138,285
Notice both answers equal 17,138,285
With that explanation out of the way, let's continue. Next, we take the number 17,138,285 and divide it by 2:
17,138,285 ÷ 2 = 8,569,142.5
If the quotient is a whole number, then 2 and 8,569,142.5 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 | 17,138,285 | |
| -1 | -17,138,285 |
Now, we try dividing 17,138,285 by 3:
17,138,285 ÷ 3 = 5,712,761.6667
If the quotient is a whole number, then 3 and 5,712,761.6667 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 | 17,138,285 | |
| -1 | -17,138,285 |
Let's try dividing by 4:
17,138,285 ÷ 4 = 4,284,571.25
If the quotient is a whole number, then 4 and 4,284,571.25 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 | 17,138,285 | |
| -1 | 17,138,285 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 89 | 95 | 445 | 1,691 | 2,027 | 8,455 | 10,135 | 38,513 | 180,403 | 192,565 | 902,015 | 3,427,657 | 17,138,285 |
| -1 | -5 | -19 | -89 | -95 | -445 | -1,691 | -2,027 | -8,455 | -10,135 | -38,513 | -180,403 | -192,565 | -902,015 | -3,427,657 | -17,138,285 |
