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 132,023,201, 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 | 132,023,201 | |
| -1 | -132,023,201 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 132,023,201.
Example:
1 x 132,023,201 = 132,023,201
and
-1 x -132,023,201 = 132,023,201
Notice both answers equal 132,023,201
With that explanation out of the way, let's continue. Next, we take the number 132,023,201 and divide it by 2:
132,023,201 ÷ 2 = 66,011,600.5
If the quotient is a whole number, then 2 and 66,011,600.5 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 | 132,023,201 | |
| -1 | -132,023,201 |
Now, we try dividing 132,023,201 by 3:
132,023,201 ÷ 3 = 44,007,733.6667
If the quotient is a whole number, then 3 and 44,007,733.6667 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 | 132,023,201 | |
| -1 | -132,023,201 |
Let's try dividing by 4:
132,023,201 ÷ 4 = 33,005,800.25
If the quotient is a whole number, then 4 and 33,005,800.25 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 | 132,023,201 | |
| -1 | 132,023,201 |
If you did it right, you will end up with this table:
| 1 | 43 | 73 | 137 | 307 | 3,139 | 5,891 | 10,001 | 13,201 | 22,411 | 42,059 | 430,043 | 963,673 | 1,808,537 | 3,070,307 | 132,023,201 |
| -1 | -43 | -73 | -137 | -307 | -3,139 | -5,891 | -10,001 | -13,201 | -22,411 | -42,059 | -430,043 | -963,673 | -1,808,537 | -3,070,307 | -132,023,201 |
