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 132,032,243, 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 | 132,032,243 | |
| -1 | -132,032,243 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 132,032,243.
Example:
1 x 132,032,243 = 132,032,243
and
-1 x -132,032,243 = 132,032,243
Notice both answers equal 132,032,243
With that explanation out of the way, let's continue. Next, we take the number 132,032,243 and divide it by 2:
132,032,243 ÷ 2 = 66,016,121.5
If the quotient is a whole number, then 2 and 66,016,121.5 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 | 132,032,243 | |
| -1 | -132,032,243 |
Now, we try dividing 132,032,243 by 3:
132,032,243 ÷ 3 = 44,010,747.6667
If the quotient is a whole number, then 3 and 44,010,747.6667 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 | 132,032,243 | |
| -1 | -132,032,243 |
Let's try dividing by 4:
132,032,243 ÷ 4 = 33,008,060.75
If the quotient is a whole number, then 4 and 33,008,060.75 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 | 132,032,243 | |
| -1 | 132,032,243 |
If you did it right, you will end up with this table:
| 1 | 7 | 37 | 61 | 137 | 259 | 427 | 959 | 2,257 | 3,721 | 5,069 | 8,357 | 15,799 | 26,047 | 35,483 | 58,499 | 137,677 | 309,209 | 509,777 | 963,739 | 2,164,463 | 3,568,439 | 18,861,749 | 132,032,243 |
| -1 | -7 | -37 | -61 | -137 | -259 | -427 | -959 | -2,257 | -3,721 | -5,069 | -8,357 | -15,799 | -26,047 | -35,483 | -58,499 | -137,677 | -309,209 | -509,777 | -963,739 | -2,164,463 | -3,568,439 | -18,861,749 | -132,032,243 |
