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 343,032,305, 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 | 343,032,305 | |
| -1 | -343,032,305 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 343,032,305.
Example:
1 x 343,032,305 = 343,032,305
and
-1 x -343,032,305 = 343,032,305
Notice both answers equal 343,032,305
With that explanation out of the way, let's continue. Next, we take the number 343,032,305 and divide it by 2:
343,032,305 ÷ 2 = 171,516,152.5
If the quotient is a whole number, then 2 and 171,516,152.5 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 | 343,032,305 | |
| -1 | -343,032,305 |
Now, we try dividing 343,032,305 by 3:
343,032,305 ÷ 3 = 114,344,101.6667
If the quotient is a whole number, then 3 and 114,344,101.6667 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 | 343,032,305 | |
| -1 | -343,032,305 |
Let's try dividing by 4:
343,032,305 ÷ 4 = 85,758,076.25
If the quotient is a whole number, then 4 and 85,758,076.25 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 | 343,032,305 | |
| -1 | 343,032,305 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 11 | 35 | 55 | 77 | 385 | 890,993 | 4,454,965 | 6,236,951 | 9,800,923 | 31,184,755 | 49,004,615 | 68,606,461 | 343,032,305 |
| -1 | -5 | -7 | -11 | -35 | -55 | -77 | -385 | -890,993 | -4,454,965 | -6,236,951 | -9,800,923 | -31,184,755 | -49,004,615 | -68,606,461 | -343,032,305 |
