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 345,215,135, 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 | 345,215,135 | |
| -1 | -345,215,135 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 345,215,135.
Example:
1 x 345,215,135 = 345,215,135
and
-1 x -345,215,135 = 345,215,135
Notice both answers equal 345,215,135
With that explanation out of the way, let's continue. Next, we take the number 345,215,135 and divide it by 2:
345,215,135 ÷ 2 = 172,607,567.5
If the quotient is a whole number, then 2 and 172,607,567.5 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 | 345,215,135 | |
| -1 | -345,215,135 |
Now, we try dividing 345,215,135 by 3:
345,215,135 ÷ 3 = 115,071,711.6667
If the quotient is a whole number, then 3 and 115,071,711.6667 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 | 345,215,135 | |
| -1 | -345,215,135 |
Let's try dividing by 4:
345,215,135 ÷ 4 = 86,303,783.75
If the quotient is a whole number, then 4 and 86,303,783.75 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 | 345,215,135 | |
| -1 | 345,215,135 |
If you did it right, you will end up with this table:
| 1 | 5 | 71 | 355 | 383 | 1,915 | 2,539 | 12,695 | 27,193 | 135,965 | 180,269 | 901,345 | 972,437 | 4,862,185 | 69,043,027 | 345,215,135 |
| -1 | -5 | -71 | -355 | -383 | -1,915 | -2,539 | -12,695 | -27,193 | -135,965 | -180,269 | -901,345 | -972,437 | -4,862,185 | -69,043,027 | -345,215,135 |
