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 18,317,959, 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 | 18,317,959 | |
| -1 | -18,317,959 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 18,317,959.
Example:
1 x 18,317,959 = 18,317,959
and
-1 x -18,317,959 = 18,317,959
Notice both answers equal 18,317,959
With that explanation out of the way, let's continue. Next, we take the number 18,317,959 and divide it by 2:
18,317,959 ÷ 2 = 9,158,979.5
If the quotient is a whole number, then 2 and 9,158,979.5 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 | 18,317,959 | |
| -1 | -18,317,959 |
Now, we try dividing 18,317,959 by 3:
18,317,959 ÷ 3 = 6,105,986.3333
If the quotient is a whole number, then 3 and 6,105,986.3333 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 | 18,317,959 | |
| -1 | -18,317,959 |
Let's try dividing by 4:
18,317,959 ÷ 4 = 4,579,489.75
If the quotient is a whole number, then 4 and 4,579,489.75 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 | 18,317,959 | |
| -1 | 18,317,959 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 23 | 187 | 253 | 391 | 4,259 | 4,301 | 46,849 | 72,403 | 97,957 | 796,433 | 1,077,527 | 1,665,269 | 18,317,959 |
| -1 | -11 | -17 | -23 | -187 | -253 | -391 | -4,259 | -4,301 | -46,849 | -72,403 | -97,957 | -796,433 | -1,077,527 | -1,665,269 | -18,317,959 |
