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 348,814,115, 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 | 348,814,115 | |
| -1 | -348,814,115 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 348,814,115.
Example:
1 x 348,814,115 = 348,814,115
and
-1 x -348,814,115 = 348,814,115
Notice both answers equal 348,814,115
With that explanation out of the way, let's continue. Next, we take the number 348,814,115 and divide it by 2:
348,814,115 ÷ 2 = 174,407,057.5
If the quotient is a whole number, then 2 and 174,407,057.5 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 | 348,814,115 | |
| -1 | -348,814,115 |
Now, we try dividing 348,814,115 by 3:
348,814,115 ÷ 3 = 116,271,371.6667
If the quotient is a whole number, then 3 and 116,271,371.6667 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 | 348,814,115 | |
| -1 | -348,814,115 |
Let's try dividing by 4:
348,814,115 ÷ 4 = 87,203,528.75
If the quotient is a whole number, then 4 and 87,203,528.75 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 | 348,814,115 | |
| -1 | 348,814,115 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 107 | 535 | 1,391 | 6,955 | 50,153 | 250,765 | 651,989 | 3,259,945 | 5,366,371 | 26,831,855 | 69,762,823 | 348,814,115 |
| -1 | -5 | -13 | -65 | -107 | -535 | -1,391 | -6,955 | -50,153 | -250,765 | -651,989 | -3,259,945 | -5,366,371 | -26,831,855 | -69,762,823 | -348,814,115 |
