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 346,168,405, 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 | 346,168,405 | |
| -1 | -346,168,405 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 346,168,405.
Example:
1 x 346,168,405 = 346,168,405
and
-1 x -346,168,405 = 346,168,405
Notice both answers equal 346,168,405
With that explanation out of the way, let's continue. Next, we take the number 346,168,405 and divide it by 2:
346,168,405 ÷ 2 = 173,084,202.5
If the quotient is a whole number, then 2 and 173,084,202.5 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 | 346,168,405 | |
| -1 | -346,168,405 |
Now, we try dividing 346,168,405 by 3:
346,168,405 ÷ 3 = 115,389,468.3333
If the quotient is a whole number, then 3 and 115,389,468.3333 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 | 346,168,405 | |
| -1 | -346,168,405 |
Let's try dividing by 4:
346,168,405 ÷ 4 = 86,542,101.25
If the quotient is a whole number, then 4 and 86,542,101.25 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 | 346,168,405 | |
| -1 | 346,168,405 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 2,203 | 2,857 | 11,015 | 14,285 | 24,233 | 31,427 | 121,165 | 157,135 | 6,293,971 | 31,469,855 | 69,233,681 | 346,168,405 |
| -1 | -5 | -11 | -55 | -2,203 | -2,857 | -11,015 | -14,285 | -24,233 | -31,427 | -121,165 | -157,135 | -6,293,971 | -31,469,855 | -69,233,681 | -346,168,405 |
