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 132,400,255, 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 | 132,400,255 | |
| -1 | -132,400,255 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 132,400,255.
Example:
1 x 132,400,255 = 132,400,255
and
-1 x -132,400,255 = 132,400,255
Notice both answers equal 132,400,255
With that explanation out of the way, let's continue. Next, we take the number 132,400,255 and divide it by 2:
132,400,255 ÷ 2 = 66,200,127.5
If the quotient is a whole number, then 2 and 66,200,127.5 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 | 132,400,255 | |
| -1 | -132,400,255 |
Now, we try dividing 132,400,255 by 3:
132,400,255 ÷ 3 = 44,133,418.3333
If the quotient is a whole number, then 3 and 44,133,418.3333 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 | 132,400,255 | |
| -1 | -132,400,255 |
Let's try dividing by 4:
132,400,255 ÷ 4 = 33,100,063.75
If the quotient is a whole number, then 4 and 33,100,063.75 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 | 132,400,255 | |
| -1 | 132,400,255 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 719 | 2,833 | 3,595 | 9,347 | 14,165 | 36,829 | 46,735 | 184,145 | 2,036,927 | 10,184,635 | 26,480,051 | 132,400,255 |
| -1 | -5 | -13 | -65 | -719 | -2,833 | -3,595 | -9,347 | -14,165 | -36,829 | -46,735 | -184,145 | -2,036,927 | -10,184,635 | -26,480,051 | -132,400,255 |
