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 18,633,311, 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 | 18,633,311 | |
| -1 | -18,633,311 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 18,633,311.
Example:
1 x 18,633,311 = 18,633,311
and
-1 x -18,633,311 = 18,633,311
Notice both answers equal 18,633,311
With that explanation out of the way, let's continue. Next, we take the number 18,633,311 and divide it by 2:
18,633,311 ÷ 2 = 9,316,655.5
If the quotient is a whole number, then 2 and 9,316,655.5 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 | 18,633,311 | |
| -1 | -18,633,311 |
Now, we try dividing 18,633,311 by 3:
18,633,311 ÷ 3 = 6,211,103.6667
If the quotient is a whole number, then 3 and 6,211,103.6667 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 | 18,633,311 | |
| -1 | -18,633,311 |
Let's try dividing by 4:
18,633,311 ÷ 4 = 4,658,327.75
If the quotient is a whole number, then 4 and 4,658,327.75 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 | 18,633,311 | |
| -1 | 18,633,311 |
If you did it right, you will end up with this table:
| 1 | 37 | 41 | 71 | 173 | 1,517 | 2,627 | 2,911 | 6,401 | 7,093 | 12,283 | 107,707 | 262,441 | 454,471 | 503,603 | 18,633,311 |
| -1 | -37 | -41 | -71 | -173 | -1,517 | -2,627 | -2,911 | -6,401 | -7,093 | -12,283 | -107,707 | -262,441 | -454,471 | -503,603 | -18,633,311 |
