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 132,301,009, 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 | 132,301,009 | |
| -1 | -132,301,009 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 132,301,009.
Example:
1 x 132,301,009 = 132,301,009
and
-1 x -132,301,009 = 132,301,009
Notice both answers equal 132,301,009
With that explanation out of the way, let's continue. Next, we take the number 132,301,009 and divide it by 2:
132,301,009 ÷ 2 = 66,150,504.5
If the quotient is a whole number, then 2 and 66,150,504.5 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 | 132,301,009 | |
| -1 | -132,301,009 |
Now, we try dividing 132,301,009 by 3:
132,301,009 ÷ 3 = 44,100,336.3333
If the quotient is a whole number, then 3 and 44,100,336.3333 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 | 132,301,009 | |
| -1 | -132,301,009 |
Let's try dividing by 4:
132,301,009 ÷ 4 = 33,075,252.25
If the quotient is a whole number, then 4 and 33,075,252.25 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 | 132,301,009 | |
| -1 | 132,301,009 |
If you did it right, you will end up with this table:
| 1 | 19 | 61 | 211 | 541 | 1,159 | 4,009 | 10,279 | 12,871 | 33,001 | 114,151 | 244,549 | 627,019 | 2,168,869 | 6,963,211 | 132,301,009 |
| -1 | -19 | -61 | -211 | -541 | -1,159 | -4,009 | -10,279 | -12,871 | -33,001 | -114,151 | -244,549 | -627,019 | -2,168,869 | -6,963,211 | -132,301,009 |
