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 9,121,333, 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 | 9,121,333 | |
| -1 | -9,121,333 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 9,121,333.
Example:
1 x 9,121,333 = 9,121,333
and
-1 x -9,121,333 = 9,121,333
Notice both answers equal 9,121,333
With that explanation out of the way, let's continue. Next, we take the number 9,121,333 and divide it by 2:
9,121,333 ÷ 2 = 4,560,666.5
If the quotient is a whole number, then 2 and 4,560,666.5 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 | 9,121,333 | |
| -1 | -9,121,333 |
Now, we try dividing 9,121,333 by 3:
9,121,333 ÷ 3 = 3,040,444.3333
If the quotient is a whole number, then 3 and 3,040,444.3333 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 | 9,121,333 | |
| -1 | -9,121,333 |
Let's try dividing by 4:
9,121,333 ÷ 4 = 2,280,333.25
If the quotient is a whole number, then 4 and 2,280,333.25 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 | 9,121,333 | |
| -1 | 9,121,333 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 149 | 221 | 277 | 1,937 | 2,533 | 3,601 | 4,709 | 32,929 | 41,273 | 61,217 | 536,549 | 701,641 | 9,121,333 |
| -1 | -13 | -17 | -149 | -221 | -277 | -1,937 | -2,533 | -3,601 | -4,709 | -32,929 | -41,273 | -61,217 | -536,549 | -701,641 | -9,121,333 |
