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 132,133,001, 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 | 132,133,001 | |
| -1 | -132,133,001 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 132,133,001.
Example:
1 x 132,133,001 = 132,133,001
and
-1 x -132,133,001 = 132,133,001
Notice both answers equal 132,133,001
With that explanation out of the way, let's continue. Next, we take the number 132,133,001 and divide it by 2:
132,133,001 ÷ 2 = 66,066,500.5
If the quotient is a whole number, then 2 and 66,066,500.5 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 | 132,133,001 | |
| -1 | -132,133,001 |
Now, we try dividing 132,133,001 by 3:
132,133,001 ÷ 3 = 44,044,333.6667
If the quotient is a whole number, then 3 and 44,044,333.6667 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 | 132,133,001 | |
| -1 | -132,133,001 |
Let's try dividing by 4:
132,133,001 ÷ 4 = 33,033,250.25
If the quotient is a whole number, then 4 and 33,033,250.25 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 | 132,133,001 | |
| -1 | 132,133,001 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 13 | 77 | 91 | 143 | 1,001 | 132,001 | 924,007 | 1,452,011 | 1,716,013 | 10,164,077 | 12,012,091 | 18,876,143 | 132,133,001 |
| -1 | -7 | -11 | -13 | -77 | -91 | -143 | -1,001 | -132,001 | -924,007 | -1,452,011 | -1,716,013 | -10,164,077 | -12,012,091 | -18,876,143 | -132,133,001 |
