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 17,231,863, 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 | 17,231,863 | |
| -1 | -17,231,863 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 17,231,863.
Example:
1 x 17,231,863 = 17,231,863
and
-1 x -17,231,863 = 17,231,863
Notice both answers equal 17,231,863
With that explanation out of the way, let's continue. Next, we take the number 17,231,863 and divide it by 2:
17,231,863 ÷ 2 = 8,615,931.5
If the quotient is a whole number, then 2 and 8,615,931.5 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 | 17,231,863 | |
| -1 | -17,231,863 |
Now, we try dividing 17,231,863 by 3:
17,231,863 ÷ 3 = 5,743,954.3333
If the quotient is a whole number, then 3 and 5,743,954.3333 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 | 17,231,863 | |
| -1 | -17,231,863 |
Let's try dividing by 4:
17,231,863 ÷ 4 = 4,307,965.75
If the quotient is a whole number, then 4 and 4,307,965.75 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 | 17,231,863 | |
| -1 | 17,231,863 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 43 | 187 | 473 | 731 | 2,143 | 8,041 | 23,573 | 36,431 | 92,149 | 400,741 | 1,013,639 | 1,566,533 | 17,231,863 |
| -1 | -11 | -17 | -43 | -187 | -473 | -731 | -2,143 | -8,041 | -23,573 | -36,431 | -92,149 | -400,741 | -1,013,639 | -1,566,533 | -17,231,863 |
