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 9,133,145, 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 | 9,133,145 | |
| -1 | -9,133,145 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 9,133,145.
Example:
1 x 9,133,145 = 9,133,145
and
-1 x -9,133,145 = 9,133,145
Notice both answers equal 9,133,145
With that explanation out of the way, let's continue. Next, we take the number 9,133,145 and divide it by 2:
9,133,145 ÷ 2 = 4,566,572.5
If the quotient is a whole number, then 2 and 4,566,572.5 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 | 9,133,145 | |
| -1 | -9,133,145 |
Now, we try dividing 9,133,145 by 3:
9,133,145 ÷ 3 = 3,044,381.6667
If the quotient is a whole number, then 3 and 3,044,381.6667 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 | 9,133,145 | |
| -1 | -9,133,145 |
Let's try dividing by 4:
9,133,145 ÷ 4 = 2,283,286.25
If the quotient is a whole number, then 4 and 2,283,286.25 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 | 9,133,145 | |
| -1 | 9,133,145 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 457 | 571 | 2,285 | 2,855 | 3,199 | 3,997 | 15,995 | 19,985 | 260,947 | 1,304,735 | 1,826,629 | 9,133,145 |
| -1 | -5 | -7 | -35 | -457 | -571 | -2,285 | -2,855 | -3,199 | -3,997 | -15,995 | -19,985 | -260,947 | -1,304,735 | -1,826,629 | -9,133,145 |
