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 342,330,305, 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 | 342,330,305 | |
| -1 | -342,330,305 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 342,330,305.
Example:
1 x 342,330,305 = 342,330,305
and
-1 x -342,330,305 = 342,330,305
Notice both answers equal 342,330,305
With that explanation out of the way, let's continue. Next, we take the number 342,330,305 and divide it by 2:
342,330,305 ÷ 2 = 171,165,152.5
If the quotient is a whole number, then 2 and 171,165,152.5 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 | 342,330,305 | |
| -1 | -342,330,305 |
Now, we try dividing 342,330,305 by 3:
342,330,305 ÷ 3 = 114,110,101.6667
If the quotient is a whole number, then 3 and 114,110,101.6667 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 | 342,330,305 | |
| -1 | -342,330,305 |
Let's try dividing by 4:
342,330,305 ÷ 4 = 85,582,576.25
If the quotient is a whole number, then 4 and 85,582,576.25 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 | 342,330,305 | |
| -1 | 342,330,305 |
If you did it right, you will end up with this table:
| 1 | 5 | 79 | 109 | 395 | 545 | 7,951 | 8,611 | 39,755 | 43,055 | 628,129 | 866,659 | 3,140,645 | 4,333,295 | 68,466,061 | 342,330,305 |
| -1 | -5 | -79 | -109 | -395 | -545 | -7,951 | -8,611 | -39,755 | -43,055 | -628,129 | -866,659 | -3,140,645 | -4,333,295 | -68,466,061 | -342,330,305 |
