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 133,321,133, 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 | 133,321,133 | |
| -1 | -133,321,133 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 133,321,133.
Example:
1 x 133,321,133 = 133,321,133
and
-1 x -133,321,133 = 133,321,133
Notice both answers equal 133,321,133
With that explanation out of the way, let's continue. Next, we take the number 133,321,133 and divide it by 2:
133,321,133 ÷ 2 = 66,660,566.5
If the quotient is a whole number, then 2 and 66,660,566.5 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 | 133,321,133 | |
| -1 | -133,321,133 |
Now, we try dividing 133,321,133 by 3:
133,321,133 ÷ 3 = 44,440,377.6667
If the quotient is a whole number, then 3 and 44,440,377.6667 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 | 133,321,133 | |
| -1 | -133,321,133 |
Let's try dividing by 4:
133,321,133 ÷ 4 = 33,330,283.25
If the quotient is a whole number, then 4 and 33,330,283.25 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 | 133,321,133 | |
| -1 | 133,321,133 |
If you did it right, you will end up with this table:
| 1 | 11 | 23 | 253 | 433 | 1,217 | 4,763 | 9,959 | 13,387 | 27,991 | 109,549 | 307,901 | 526,961 | 5,796,571 | 12,120,103 | 133,321,133 |
| -1 | -11 | -23 | -253 | -433 | -1,217 | -4,763 | -9,959 | -13,387 | -27,991 | -109,549 | -307,901 | -526,961 | -5,796,571 | -12,120,103 | -133,321,133 |
