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 16,217,033, 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 | 16,217,033 | |
| -1 | -16,217,033 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,217,033.
Example:
1 x 16,217,033 = 16,217,033
and
-1 x -16,217,033 = 16,217,033
Notice both answers equal 16,217,033
With that explanation out of the way, let's continue. Next, we take the number 16,217,033 and divide it by 2:
16,217,033 ÷ 2 = 8,108,516.5
If the quotient is a whole number, then 2 and 8,108,516.5 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 | 16,217,033 | |
| -1 | -16,217,033 |
Now, we try dividing 16,217,033 by 3:
16,217,033 ÷ 3 = 5,405,677.6667
If the quotient is a whole number, then 3 and 5,405,677.6667 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 | 16,217,033 | |
| -1 | -16,217,033 |
Let's try dividing by 4:
16,217,033 ÷ 4 = 4,054,258.25
If the quotient is a whole number, then 4 and 4,054,258.25 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 | 16,217,033 | |
| -1 | 16,217,033 |
If you did it right, you will end up with this table:
| 1 | 7 | 61 | 163 | 233 | 427 | 1,141 | 1,631 | 9,943 | 14,213 | 37,979 | 69,601 | 99,491 | 265,853 | 2,316,719 | 16,217,033 |
| -1 | -7 | -61 | -163 | -233 | -427 | -1,141 | -1,631 | -9,943 | -14,213 | -37,979 | -69,601 | -99,491 | -265,853 | -2,316,719 | -16,217,033 |
