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 133,311,233, 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 | 133,311,233 | |
| -1 | -133,311,233 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 133,311,233.
Example:
1 x 133,311,233 = 133,311,233
and
-1 x -133,311,233 = 133,311,233
Notice both answers equal 133,311,233
With that explanation out of the way, let's continue. Next, we take the number 133,311,233 and divide it by 2:
133,311,233 ÷ 2 = 66,655,616.5
If the quotient is a whole number, then 2 and 66,655,616.5 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 | 133,311,233 | |
| -1 | -133,311,233 |
Now, we try dividing 133,311,233 by 3:
133,311,233 ÷ 3 = 44,437,077.6667
If the quotient is a whole number, then 3 and 44,437,077.6667 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 | 133,311,233 | |
| -1 | -133,311,233 |
Let's try dividing by 4:
133,311,233 ÷ 4 = 33,327,808.25
If the quotient is a whole number, then 4 and 33,327,808.25 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 | 133,311,233 | |
| -1 | 133,311,233 |
If you did it right, you will end up with this table:
| 1 | 11 | 71 | 131 | 781 | 1,303 | 1,441 | 9,301 | 14,333 | 92,513 | 102,311 | 170,693 | 1,017,643 | 1,877,623 | 12,119,203 | 133,311,233 |
| -1 | -11 | -71 | -131 | -781 | -1,303 | -1,441 | -9,301 | -14,333 | -92,513 | -102,311 | -170,693 | -1,017,643 | -1,877,623 | -12,119,203 | -133,311,233 |
