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 13,022,233, 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 | 13,022,233 | |
| -1 | -13,022,233 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,022,233.
Example:
1 x 13,022,233 = 13,022,233
and
-1 x -13,022,233 = 13,022,233
Notice both answers equal 13,022,233
With that explanation out of the way, let's continue. Next, we take the number 13,022,233 and divide it by 2:
13,022,233 ÷ 2 = 6,511,116.5
If the quotient is a whole number, then 2 and 6,511,116.5 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 | 13,022,233 | |
| -1 | -13,022,233 |
Now, we try dividing 13,022,233 by 3:
13,022,233 ÷ 3 = 4,340,744.3333
If the quotient is a whole number, then 3 and 4,340,744.3333 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 | 13,022,233 | |
| -1 | -13,022,233 |
Let's try dividing by 4:
13,022,233 ÷ 4 = 3,255,558.25
If the quotient is a whole number, then 4 and 3,255,558.25 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 | 13,022,233 | |
| -1 | 13,022,233 |
If you did it right, you will end up with this table:
| 1 | 7 | 101 | 113 | 163 | 707 | 791 | 1,141 | 11,413 | 16,463 | 18,419 | 79,891 | 115,241 | 128,933 | 1,860,319 | 13,022,233 |
| -1 | -7 | -101 | -113 | -163 | -707 | -791 | -1,141 | -11,413 | -16,463 | -18,419 | -79,891 | -115,241 | -128,933 | -1,860,319 | -13,022,233 |
