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 132,155,309, 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 | 132,155,309 | |
| -1 | -132,155,309 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 132,155,309.
Example:
1 x 132,155,309 = 132,155,309
and
-1 x -132,155,309 = 132,155,309
Notice both answers equal 132,155,309
With that explanation out of the way, let's continue. Next, we take the number 132,155,309 and divide it by 2:
132,155,309 ÷ 2 = 66,077,654.5
If the quotient is a whole number, then 2 and 66,077,654.5 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 | 132,155,309 | |
| -1 | -132,155,309 |
Now, we try dividing 132,155,309 by 3:
132,155,309 ÷ 3 = 44,051,769.6667
If the quotient is a whole number, then 3 and 44,051,769.6667 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 | 132,155,309 | |
| -1 | -132,155,309 |
Let's try dividing by 4:
132,155,309 ÷ 4 = 33,038,827.25
If the quotient is a whole number, then 4 and 33,038,827.25 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 | 132,155,309 | |
| -1 | 132,155,309 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 23 | 143 | 253 | 299 | 529 | 1,747 | 3,289 | 5,819 | 6,877 | 19,217 | 22,711 | 40,181 | 75,647 | 249,821 | 441,991 | 522,353 | 924,163 | 5,745,883 | 10,165,793 | 12,014,119 | 132,155,309 |
| -1 | -11 | -13 | -23 | -143 | -253 | -299 | -529 | -1,747 | -3,289 | -5,819 | -6,877 | -19,217 | -22,711 | -40,181 | -75,647 | -249,821 | -441,991 | -522,353 | -924,163 | -5,745,883 | -10,165,793 | -12,014,119 | -132,155,309 |
