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 17,914,589, 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 | 17,914,589 | |
| -1 | -17,914,589 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 17,914,589.
Example:
1 x 17,914,589 = 17,914,589
and
-1 x -17,914,589 = 17,914,589
Notice both answers equal 17,914,589
With that explanation out of the way, let's continue. Next, we take the number 17,914,589 and divide it by 2:
17,914,589 ÷ 2 = 8,957,294.5
If the quotient is a whole number, then 2 and 8,957,294.5 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 | 17,914,589 | |
| -1 | -17,914,589 |
Now, we try dividing 17,914,589 by 3:
17,914,589 ÷ 3 = 5,971,529.6667
If the quotient is a whole number, then 3 and 5,971,529.6667 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 | 17,914,589 | |
| -1 | -17,914,589 |
Let's try dividing by 4:
17,914,589 ÷ 4 = 4,478,647.25
If the quotient is a whole number, then 4 and 4,478,647.25 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 | 17,914,589 | |
| -1 | 17,914,589 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 197 | 1,181 | 1,379 | 2,167 | 8,267 | 12,991 | 15,169 | 90,937 | 232,657 | 1,628,599 | 2,559,227 | 17,914,589 |
| -1 | -7 | -11 | -77 | -197 | -1,181 | -1,379 | -2,167 | -8,267 | -12,991 | -15,169 | -90,937 | -232,657 | -1,628,599 | -2,559,227 | -17,914,589 |
