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 132,655,645, 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 | 132,655,645 | |
| -1 | -132,655,645 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 132,655,645.
Example:
1 x 132,655,645 = 132,655,645
and
-1 x -132,655,645 = 132,655,645
Notice both answers equal 132,655,645
With that explanation out of the way, let's continue. Next, we take the number 132,655,645 and divide it by 2:
132,655,645 ÷ 2 = 66,327,822.5
If the quotient is a whole number, then 2 and 66,327,822.5 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 | 132,655,645 | |
| -1 | -132,655,645 |
Now, we try dividing 132,655,645 by 3:
132,655,645 ÷ 3 = 44,218,548.3333
If the quotient is a whole number, then 3 and 44,218,548.3333 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 | 132,655,645 | |
| -1 | -132,655,645 |
Let's try dividing by 4:
132,655,645 ÷ 4 = 33,163,911.25
If the quotient is a whole number, then 4 and 33,163,911.25 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 | 132,655,645 | |
| -1 | 132,655,645 |
If you did it right, you will end up with this table:
| 1 | 5 | 43 | 67 | 215 | 335 | 2,881 | 9,209 | 14,405 | 46,045 | 395,987 | 617,003 | 1,979,935 | 3,085,015 | 26,531,129 | 132,655,645 |
| -1 | -5 | -43 | -67 | -215 | -335 | -2,881 | -9,209 | -14,405 | -46,045 | -395,987 | -617,003 | -1,979,935 | -3,085,015 | -26,531,129 | -132,655,645 |
