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 132,550,405, 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 | 132,550,405 | |
| -1 | -132,550,405 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 132,550,405.
Example:
1 x 132,550,405 = 132,550,405
and
-1 x -132,550,405 = 132,550,405
Notice both answers equal 132,550,405
With that explanation out of the way, let's continue. Next, we take the number 132,550,405 and divide it by 2:
132,550,405 ÷ 2 = 66,275,202.5
If the quotient is a whole number, then 2 and 66,275,202.5 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 | 132,550,405 | |
| -1 | -132,550,405 |
Now, we try dividing 132,550,405 by 3:
132,550,405 ÷ 3 = 44,183,468.3333
If the quotient is a whole number, then 3 and 44,183,468.3333 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 | 132,550,405 | |
| -1 | -132,550,405 |
Let's try dividing by 4:
132,550,405 ÷ 4 = 33,137,601.25
If the quotient is a whole number, then 4 and 33,137,601.25 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 | 132,550,405 | |
| -1 | 132,550,405 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 167 | 835 | 2,171 | 10,855 | 12,211 | 61,055 | 158,743 | 793,715 | 2,039,237 | 10,196,185 | 26,510,081 | 132,550,405 |
| -1 | -5 | -13 | -65 | -167 | -835 | -2,171 | -10,855 | -12,211 | -61,055 | -158,743 | -793,715 | -2,039,237 | -10,196,185 | -26,510,081 | -132,550,405 |
