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 343,400,255, 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 | 343,400,255 | |
| -1 | -343,400,255 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 343,400,255.
Example:
1 x 343,400,255 = 343,400,255
and
-1 x -343,400,255 = 343,400,255
Notice both answers equal 343,400,255
With that explanation out of the way, let's continue. Next, we take the number 343,400,255 and divide it by 2:
343,400,255 ÷ 2 = 171,700,127.5
If the quotient is a whole number, then 2 and 171,700,127.5 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 | 343,400,255 | |
| -1 | -343,400,255 |
Now, we try dividing 343,400,255 by 3:
343,400,255 ÷ 3 = 114,466,751.6667
If the quotient is a whole number, then 3 and 114,466,751.6667 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 | 343,400,255 | |
| -1 | -343,400,255 |
Let's try dividing by 4:
343,400,255 ÷ 4 = 85,850,063.75
If the quotient is a whole number, then 4 and 85,850,063.75 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 | 343,400,255 | |
| -1 | 343,400,255 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 17 | 55 | 85 | 187 | 935 | 367,273 | 1,836,365 | 4,040,003 | 6,243,641 | 20,200,015 | 31,218,205 | 68,680,051 | 343,400,255 |
| -1 | -5 | -11 | -17 | -55 | -85 | -187 | -935 | -367,273 | -1,836,365 | -4,040,003 | -6,243,641 | -20,200,015 | -31,218,205 | -68,680,051 | -343,400,255 |
