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 132,543,005, 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 | 132,543,005 | |
| -1 | -132,543,005 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 132,543,005.
Example:
1 x 132,543,005 = 132,543,005
and
-1 x -132,543,005 = 132,543,005
Notice both answers equal 132,543,005
With that explanation out of the way, let's continue. Next, we take the number 132,543,005 and divide it by 2:
132,543,005 ÷ 2 = 66,271,502.5
If the quotient is a whole number, then 2 and 66,271,502.5 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 | 132,543,005 | |
| -1 | -132,543,005 |
Now, we try dividing 132,543,005 by 3:
132,543,005 ÷ 3 = 44,181,001.6667
If the quotient is a whole number, then 3 and 44,181,001.6667 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 | 132,543,005 | |
| -1 | -132,543,005 |
Let's try dividing by 4:
132,543,005 ÷ 4 = 33,135,751.25
If the quotient is a whole number, then 4 and 33,135,751.25 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 | 132,543,005 | |
| -1 | 132,543,005 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 727 | 3,635 | 5,089 | 5,209 | 25,445 | 26,045 | 36,463 | 182,315 | 3,786,943 | 18,934,715 | 26,508,601 | 132,543,005 |
| -1 | -5 | -7 | -35 | -727 | -3,635 | -5,089 | -5,209 | -25,445 | -26,045 | -36,463 | -182,315 | -3,786,943 | -18,934,715 | -26,508,601 | -132,543,005 |
