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 342,140,315, 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 | 342,140,315 | |
| -1 | -342,140,315 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 342,140,315.
Example:
1 x 342,140,315 = 342,140,315
and
-1 x -342,140,315 = 342,140,315
Notice both answers equal 342,140,315
With that explanation out of the way, let's continue. Next, we take the number 342,140,315 and divide it by 2:
342,140,315 ÷ 2 = 171,070,157.5
If the quotient is a whole number, then 2 and 171,070,157.5 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 | 342,140,315 | |
| -1 | -342,140,315 |
Now, we try dividing 342,140,315 by 3:
342,140,315 ÷ 3 = 114,046,771.6667
If the quotient is a whole number, then 3 and 114,046,771.6667 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 | 342,140,315 | |
| -1 | -342,140,315 |
Let's try dividing by 4:
342,140,315 ÷ 4 = 85,535,078.75
If the quotient is a whole number, then 4 and 85,535,078.75 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 | 342,140,315 | |
| -1 | 342,140,315 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 19 | 55 | 95 | 209 | 1,045 | 327,407 | 1,637,035 | 3,601,477 | 6,220,733 | 18,007,385 | 31,103,665 | 68,428,063 | 342,140,315 |
| -1 | -5 | -11 | -19 | -55 | -95 | -209 | -1,045 | -327,407 | -1,637,035 | -3,601,477 | -6,220,733 | -18,007,385 | -31,103,665 | -68,428,063 | -342,140,315 |
