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 132,542,555, 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 | 132,542,555 | |
| -1 | -132,542,555 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 132,542,555.
Example:
1 x 132,542,555 = 132,542,555
and
-1 x -132,542,555 = 132,542,555
Notice both answers equal 132,542,555
With that explanation out of the way, let's continue. Next, we take the number 132,542,555 and divide it by 2:
132,542,555 ÷ 2 = 66,271,277.5
If the quotient is a whole number, then 2 and 66,271,277.5 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 | 132,542,555 | |
| -1 | -132,542,555 |
Now, we try dividing 132,542,555 by 3:
132,542,555 ÷ 3 = 44,180,851.6667
If the quotient is a whole number, then 3 and 44,180,851.6667 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 | 132,542,555 | |
| -1 | -132,542,555 |
Let's try dividing by 4:
132,542,555 ÷ 4 = 33,135,638.75
If the quotient is a whole number, then 4 and 33,135,638.75 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 | 132,542,555 | |
| -1 | 132,542,555 |
If you did it right, you will end up with this table:
| 1 | 5 | 43 | 215 | 449 | 1,373 | 2,245 | 6,865 | 19,307 | 59,039 | 96,535 | 295,195 | 616,477 | 3,082,385 | 26,508,511 | 132,542,555 |
| -1 | -5 | -43 | -215 | -449 | -1,373 | -2,245 | -6,865 | -19,307 | -59,039 | -96,535 | -295,195 | -616,477 | -3,082,385 | -26,508,511 | -132,542,555 |
