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 1,216,033, 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 | 1,216,033 | |
| -1 | -1,216,033 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,216,033.
Example:
1 x 1,216,033 = 1,216,033
and
-1 x -1,216,033 = 1,216,033
Notice both answers equal 1,216,033
With that explanation out of the way, let's continue. Next, we take the number 1,216,033 and divide it by 2:
1,216,033 ÷ 2 = 608,016.5
If the quotient is a whole number, then 2 and 608,016.5 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 | 1,216,033 | |
| -1 | -1,216,033 |
Now, we try dividing 1,216,033 by 3:
1,216,033 ÷ 3 = 405,344.3333
If the quotient is a whole number, then 3 and 405,344.3333 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 | 1,216,033 | |
| -1 | -1,216,033 |
Let's try dividing by 4:
1,216,033 ÷ 4 = 304,008.25
If the quotient is a whole number, then 4 and 304,008.25 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 | 1,216,033 | |
| -1 | 1,216,033 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 23 | 49 | 83 | 91 | 161 | 299 | 581 | 637 | 1,079 | 1,127 | 1,909 | 2,093 | 4,067 | 7,553 | 13,363 | 14,651 | 24,817 | 52,871 | 93,541 | 173,719 | 1,216,033 |
| -1 | -7 | -13 | -23 | -49 | -83 | -91 | -161 | -299 | -581 | -637 | -1,079 | -1,127 | -1,909 | -2,093 | -4,067 | -7,553 | -13,363 | -14,651 | -24,817 | -52,871 | -93,541 | -173,719 | -1,216,033 |
