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 347,502,125, 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 | 347,502,125 | |
| -1 | -347,502,125 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 347,502,125.
Example:
1 x 347,502,125 = 347,502,125
and
-1 x -347,502,125 = 347,502,125
Notice both answers equal 347,502,125
With that explanation out of the way, let's continue. Next, we take the number 347,502,125 and divide it by 2:
347,502,125 ÷ 2 = 173,751,062.5
If the quotient is a whole number, then 2 and 173,751,062.5 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 | 347,502,125 | |
| -1 | -347,502,125 |
Now, we try dividing 347,502,125 by 3:
347,502,125 ÷ 3 = 115,834,041.6667
If the quotient is a whole number, then 3 and 115,834,041.6667 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 | 347,502,125 | |
| -1 | -347,502,125 |
Let's try dividing by 4:
347,502,125 ÷ 4 = 86,875,531.25
If the quotient is a whole number, then 4 and 86,875,531.25 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 | 347,502,125 | |
| -1 | 347,502,125 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 125 | 641 | 3,205 | 4,337 | 16,025 | 21,685 | 80,125 | 108,425 | 542,125 | 2,780,017 | 13,900,085 | 69,500,425 | 347,502,125 |
| -1 | -5 | -25 | -125 | -641 | -3,205 | -4,337 | -16,025 | -21,685 | -80,125 | -108,425 | -542,125 | -2,780,017 | -13,900,085 | -69,500,425 | -347,502,125 |
