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 17,653,727, 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 | 17,653,727 | |
| -1 | -17,653,727 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 17,653,727.
Example:
1 x 17,653,727 = 17,653,727
and
-1 x -17,653,727 = 17,653,727
Notice both answers equal 17,653,727
With that explanation out of the way, let's continue. Next, we take the number 17,653,727 and divide it by 2:
17,653,727 ÷ 2 = 8,826,863.5
If the quotient is a whole number, then 2 and 8,826,863.5 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 | 17,653,727 | |
| -1 | -17,653,727 |
Now, we try dividing 17,653,727 by 3:
17,653,727 ÷ 3 = 5,884,575.6667
If the quotient is a whole number, then 3 and 5,884,575.6667 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 | 17,653,727 | |
| -1 | -17,653,727 |
Let's try dividing by 4:
17,653,727 ÷ 4 = 4,413,431.75
If the quotient is a whole number, then 4 and 4,413,431.75 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 | 17,653,727 | |
| -1 | 17,653,727 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 91 | 419 | 463 | 2,933 | 3,241 | 5,447 | 6,019 | 38,129 | 42,133 | 193,997 | 1,357,979 | 2,521,961 | 17,653,727 |
| -1 | -7 | -13 | -91 | -419 | -463 | -2,933 | -3,241 | -5,447 | -6,019 | -38,129 | -42,133 | -193,997 | -1,357,979 | -2,521,961 | -17,653,727 |
