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 344,103,331, 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 | 344,103,331 | |
| -1 | -344,103,331 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 344,103,331.
Example:
1 x 344,103,331 = 344,103,331
and
-1 x -344,103,331 = 344,103,331
Notice both answers equal 344,103,331
With that explanation out of the way, let's continue. Next, we take the number 344,103,331 and divide it by 2:
344,103,331 ÷ 2 = 172,051,665.5
If the quotient is a whole number, then 2 and 172,051,665.5 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 | 344,103,331 | |
| -1 | -344,103,331 |
Now, we try dividing 344,103,331 by 3:
344,103,331 ÷ 3 = 114,701,110.3333
If the quotient is a whole number, then 3 and 114,701,110.3333 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 | 344,103,331 | |
| -1 | -344,103,331 |
Let's try dividing by 4:
344,103,331 ÷ 4 = 86,025,832.75
If the quotient is a whole number, then 4 and 86,025,832.75 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 | 344,103,331 | |
| -1 | 344,103,331 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 143 | 419 | 4,609 | 5,447 | 5,743 | 59,917 | 63,173 | 74,659 | 821,249 | 2,406,317 | 26,469,487 | 31,282,121 | 344,103,331 |
| -1 | -11 | -13 | -143 | -419 | -4,609 | -5,447 | -5,743 | -59,917 | -63,173 | -74,659 | -821,249 | -2,406,317 | -26,469,487 | -31,282,121 | -344,103,331 |
