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 17,846,969, 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 | 17,846,969 | |
| -1 | -17,846,969 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 17,846,969.
Example:
1 x 17,846,969 = 17,846,969
and
-1 x -17,846,969 = 17,846,969
Notice both answers equal 17,846,969
With that explanation out of the way, let's continue. Next, we take the number 17,846,969 and divide it by 2:
17,846,969 ÷ 2 = 8,923,484.5
If the quotient is a whole number, then 2 and 8,923,484.5 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 | 17,846,969 | |
| -1 | -17,846,969 |
Now, we try dividing 17,846,969 by 3:
17,846,969 ÷ 3 = 5,948,989.6667
If the quotient is a whole number, then 3 and 5,948,989.6667 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 | 17,846,969 | |
| -1 | -17,846,969 |
Let's try dividing by 4:
17,846,969 ÷ 4 = 4,461,742.25
If the quotient is a whole number, then 4 and 4,461,742.25 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 | 17,846,969 | |
| -1 | 17,846,969 |
If you did it right, you will end up with this table:
| 1 | 7 | 59 | 79 | 413 | 547 | 553 | 3,829 | 4,661 | 32,273 | 32,627 | 43,213 | 225,911 | 302,491 | 2,549,567 | 17,846,969 |
| -1 | -7 | -59 | -79 | -413 | -547 | -553 | -3,829 | -4,661 | -32,273 | -32,627 | -43,213 | -225,911 | -302,491 | -2,549,567 | -17,846,969 |
