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 123,132,233, 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 | 123,132,233 | |
| -1 | -123,132,233 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 123,132,233.
Example:
1 x 123,132,233 = 123,132,233
and
-1 x -123,132,233 = 123,132,233
Notice both answers equal 123,132,233
With that explanation out of the way, let's continue. Next, we take the number 123,132,233 and divide it by 2:
123,132,233 ÷ 2 = 61,566,116.5
If the quotient is a whole number, then 2 and 61,566,116.5 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 | 123,132,233 | |
| -1 | -123,132,233 |
Now, we try dividing 123,132,233 by 3:
123,132,233 ÷ 3 = 41,044,077.6667
If the quotient is a whole number, then 3 and 41,044,077.6667 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 | 123,132,233 | |
| -1 | -123,132,233 |
Let's try dividing by 4:
123,132,233 ÷ 4 = 30,783,058.25
If the quotient is a whole number, then 4 and 30,783,058.25 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 | 123,132,233 | |
| -1 | 123,132,233 |
If you did it right, you will end up with this table:
| 1 | 7 | 59 | 281 | 413 | 1,061 | 1,967 | 7,427 | 16,579 | 62,599 | 116,053 | 298,141 | 438,193 | 2,086,987 | 17,590,319 | 123,132,233 |
| -1 | -7 | -59 | -281 | -413 | -1,061 | -1,967 | -7,427 | -16,579 | -62,599 | -116,053 | -298,141 | -438,193 | -2,086,987 | -17,590,319 | -123,132,233 |
