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 17,186,875, 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 | 17,186,875 | |
| -1 | -17,186,875 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 17,186,875.
Example:
1 x 17,186,875 = 17,186,875
and
-1 x -17,186,875 = 17,186,875
Notice both answers equal 17,186,875
With that explanation out of the way, let's continue. Next, we take the number 17,186,875 and divide it by 2:
17,186,875 ÷ 2 = 8,593,437.5
If the quotient is a whole number, then 2 and 8,593,437.5 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 | 17,186,875 | |
| -1 | -17,186,875 |
Now, we try dividing 17,186,875 by 3:
17,186,875 ÷ 3 = 5,728,958.3333
If the quotient is a whole number, then 3 and 5,728,958.3333 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 | 17,186,875 | |
| -1 | -17,186,875 |
Let's try dividing by 4:
17,186,875 ÷ 4 = 4,296,718.75
If the quotient is a whole number, then 4 and 4,296,718.75 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 | 17,186,875 | |
| -1 | 17,186,875 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 107 | 125 | 257 | 535 | 625 | 1,285 | 2,675 | 6,425 | 13,375 | 27,499 | 32,125 | 66,875 | 137,495 | 160,625 | 687,475 | 3,437,375 | 17,186,875 |
| -1 | -5 | -25 | -107 | -125 | -257 | -535 | -625 | -1,285 | -2,675 | -6,425 | -13,375 | -27,499 | -32,125 | -66,875 | -137,495 | -160,625 | -687,475 | -3,437,375 | -17,186,875 |
