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 2,229,023, 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 | 2,229,023 | |
| -1 | -2,229,023 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,229,023.
Example:
1 x 2,229,023 = 2,229,023
and
-1 x -2,229,023 = 2,229,023
Notice both answers equal 2,229,023
With that explanation out of the way, let's continue. Next, we take the number 2,229,023 and divide it by 2:
2,229,023 ÷ 2 = 1,114,511.5
If the quotient is a whole number, then 2 and 1,114,511.5 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 | 2,229,023 | |
| -1 | -2,229,023 |
Now, we try dividing 2,229,023 by 3:
2,229,023 ÷ 3 = 743,007.6667
If the quotient is a whole number, then 3 and 743,007.6667 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 | 2,229,023 | |
| -1 | -2,229,023 |
Let's try dividing by 4:
2,229,023 ÷ 4 = 557,255.75
If the quotient is a whole number, then 4 and 557,255.75 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 | 2,229,023 | |
| -1 | 2,229,023 |
If you did it right, you will end up with this table:
| 1 | 17 | 19 | 67 | 103 | 323 | 1,139 | 1,273 | 1,751 | 1,957 | 6,901 | 21,641 | 33,269 | 117,317 | 131,119 | 2,229,023 |
| -1 | -17 | -19 | -67 | -103 | -323 | -1,139 | -1,273 | -1,751 | -1,957 | -6,901 | -21,641 | -33,269 | -117,317 | -131,119 | -2,229,023 |
