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 343,915, 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 | 343,915 | |
| -1 | -343,915 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 343,915.
Example:
1 x 343,915 = 343,915
and
-1 x -343,915 = 343,915
Notice both answers equal 343,915
With that explanation out of the way, let's continue. Next, we take the number 343,915 and divide it by 2:
343,915 ÷ 2 = 171,957.5
If the quotient is a whole number, then 2 and 171,957.5 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 | 343,915 | |
| -1 | -343,915 |
Now, we try dividing 343,915 by 3:
343,915 ÷ 3 = 114,638.3333
If the quotient is a whole number, then 3 and 114,638.3333 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 | 343,915 | |
| -1 | -343,915 |
Let's try dividing by 4:
343,915 ÷ 4 = 85,978.75
If the quotient is a whole number, then 4 and 85,978.75 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 | 343,915 | |
| -1 | 343,915 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 13 | 37 | 55 | 65 | 143 | 169 | 185 | 407 | 481 | 715 | 845 | 1,859 | 2,035 | 2,405 | 5,291 | 6,253 | 9,295 | 26,455 | 31,265 | 68,783 | 343,915 |
| -1 | -5 | -11 | -13 | -37 | -55 | -65 | -143 | -169 | -185 | -407 | -481 | -715 | -845 | -1,859 | -2,035 | -2,405 | -5,291 | -6,253 | -9,295 | -26,455 | -31,265 | -68,783 | -343,915 |
