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 341,313,215, 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 | 341,313,215 | |
| -1 | -341,313,215 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 341,313,215.
Example:
1 x 341,313,215 = 341,313,215
and
-1 x -341,313,215 = 341,313,215
Notice both answers equal 341,313,215
With that explanation out of the way, let's continue. Next, we take the number 341,313,215 and divide it by 2:
341,313,215 ÷ 2 = 170,656,607.5
If the quotient is a whole number, then 2 and 170,656,607.5 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 | 341,313,215 | |
| -1 | -341,313,215 |
Now, we try dividing 341,313,215 by 3:
341,313,215 ÷ 3 = 113,771,071.6667
If the quotient is a whole number, then 3 and 113,771,071.6667 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 | 341,313,215 | |
| -1 | -341,313,215 |
Let's try dividing by 4:
341,313,215 ÷ 4 = 85,328,303.75
If the quotient is a whole number, then 4 and 85,328,303.75 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 | 341,313,215 | |
| -1 | 341,313,215 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 115 | 1,231 | 2,411 | 6,155 | 12,055 | 28,313 | 55,453 | 141,565 | 277,265 | 2,967,941 | 14,839,705 | 68,262,643 | 341,313,215 |
| -1 | -5 | -23 | -115 | -1,231 | -2,411 | -6,155 | -12,055 | -28,313 | -55,453 | -141,565 | -277,265 | -2,967,941 | -14,839,705 | -68,262,643 | -341,313,215 |
