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 14,218,085, 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 | 14,218,085 | |
| -1 | -14,218,085 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 14,218,085.
Example:
1 x 14,218,085 = 14,218,085
and
-1 x -14,218,085 = 14,218,085
Notice both answers equal 14,218,085
With that explanation out of the way, let's continue. Next, we take the number 14,218,085 and divide it by 2:
14,218,085 ÷ 2 = 7,109,042.5
If the quotient is a whole number, then 2 and 7,109,042.5 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 | 14,218,085 | |
| -1 | -14,218,085 |
Now, we try dividing 14,218,085 by 3:
14,218,085 ÷ 3 = 4,739,361.6667
If the quotient is a whole number, then 3 and 4,739,361.6667 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 | 14,218,085 | |
| -1 | -14,218,085 |
Let's try dividing by 4:
14,218,085 ÷ 4 = 3,554,521.25
If the quotient is a whole number, then 4 and 3,554,521.25 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 | 14,218,085 | |
| -1 | 14,218,085 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 49 | 131 | 245 | 443 | 655 | 917 | 2,215 | 3,101 | 4,585 | 6,419 | 15,505 | 21,707 | 32,095 | 58,033 | 108,535 | 290,165 | 406,231 | 2,031,155 | 2,843,617 | 14,218,085 |
| -1 | -5 | -7 | -35 | -49 | -131 | -245 | -443 | -655 | -917 | -2,215 | -3,101 | -4,585 | -6,419 | -15,505 | -21,707 | -32,095 | -58,033 | -108,535 | -290,165 | -406,231 | -2,031,155 | -2,843,617 | -14,218,085 |
