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 2,258,333, 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 | 2,258,333 | |
| -1 | -2,258,333 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,258,333.
Example:
1 x 2,258,333 = 2,258,333
and
-1 x -2,258,333 = 2,258,333
Notice both answers equal 2,258,333
With that explanation out of the way, let's continue. Next, we take the number 2,258,333 and divide it by 2:
2,258,333 ÷ 2 = 1,129,166.5
If the quotient is a whole number, then 2 and 1,129,166.5 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 | 2,258,333 | |
| -1 | -2,258,333 |
Now, we try dividing 2,258,333 by 3:
2,258,333 ÷ 3 = 752,777.6667
If the quotient is a whole number, then 3 and 752,777.6667 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 | 2,258,333 | |
| -1 | -2,258,333 |
Let's try dividing by 4:
2,258,333 ÷ 4 = 564,583.25
If the quotient is a whole number, then 4 and 564,583.25 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 | 2,258,333 | |
| -1 | 2,258,333 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 139 | 211 | 973 | 1,477 | 1,529 | 2,321 | 10,703 | 16,247 | 29,329 | 205,303 | 322,619 | 2,258,333 |
| -1 | -7 | -11 | -77 | -139 | -211 | -973 | -1,477 | -1,529 | -2,321 | -10,703 | -16,247 | -29,329 | -205,303 | -322,619 | -2,258,333 |
