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 132,155,305, 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 | 132,155,305 | |
| -1 | -132,155,305 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 132,155,305.
Example:
1 x 132,155,305 = 132,155,305
and
-1 x -132,155,305 = 132,155,305
Notice both answers equal 132,155,305
With that explanation out of the way, let's continue. Next, we take the number 132,155,305 and divide it by 2:
132,155,305 ÷ 2 = 66,077,652.5
If the quotient is a whole number, then 2 and 66,077,652.5 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 | 132,155,305 | |
| -1 | -132,155,305 |
Now, we try dividing 132,155,305 by 3:
132,155,305 ÷ 3 = 44,051,768.3333
If the quotient is a whole number, then 3 and 44,051,768.3333 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 | 132,155,305 | |
| -1 | -132,155,305 |
Let's try dividing by 4:
132,155,305 ÷ 4 = 33,038,826.25
If the quotient is a whole number, then 4 and 33,038,826.25 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 | 132,155,305 | |
| -1 | 132,155,305 |
If you did it right, you will end up with this table:
| 1 | 5 | 37 | 47 | 185 | 235 | 1,739 | 8,695 | 15,199 | 75,995 | 562,363 | 714,353 | 2,811,815 | 3,571,765 | 26,431,061 | 132,155,305 |
| -1 | -5 | -37 | -47 | -185 | -235 | -1,739 | -8,695 | -15,199 | -75,995 | -562,363 | -714,353 | -2,811,815 | -3,571,765 | -26,431,061 | -132,155,305 |
