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 164,032,135, 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 | 164,032,135 | |
| -1 | -164,032,135 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 164,032,135.
Example:
1 x 164,032,135 = 164,032,135
and
-1 x -164,032,135 = 164,032,135
Notice both answers equal 164,032,135
With that explanation out of the way, let's continue. Next, we take the number 164,032,135 and divide it by 2:
164,032,135 ÷ 2 = 82,016,067.5
If the quotient is a whole number, then 2 and 82,016,067.5 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 | 164,032,135 | |
| -1 | -164,032,135 |
Now, we try dividing 164,032,135 by 3:
164,032,135 ÷ 3 = 54,677,378.3333
If the quotient is a whole number, then 3 and 54,677,378.3333 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 | 164,032,135 | |
| -1 | -164,032,135 |
Let's try dividing by 4:
164,032,135 ÷ 4 = 41,008,033.75
If the quotient is a whole number, then 4 and 41,008,033.75 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 | 164,032,135 | |
| -1 | 164,032,135 |
If you did it right, you will end up with this table:
| 1 | 5 | 103 | 431 | 515 | 739 | 2,155 | 3,695 | 44,393 | 76,117 | 221,965 | 318,509 | 380,585 | 1,592,545 | 32,806,427 | 164,032,135 |
| -1 | -5 | -103 | -431 | -515 | -739 | -2,155 | -3,695 | -44,393 | -76,117 | -221,965 | -318,509 | -380,585 | -1,592,545 | -32,806,427 | -164,032,135 |
