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 350,160,215, 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 | 350,160,215 | |
| -1 | -350,160,215 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 350,160,215.
Example:
1 x 350,160,215 = 350,160,215
and
-1 x -350,160,215 = 350,160,215
Notice both answers equal 350,160,215
With that explanation out of the way, let's continue. Next, we take the number 350,160,215 and divide it by 2:
350,160,215 ÷ 2 = 175,080,107.5
If the quotient is a whole number, then 2 and 175,080,107.5 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 | 350,160,215 | |
| -1 | -350,160,215 |
Now, we try dividing 350,160,215 by 3:
350,160,215 ÷ 3 = 116,720,071.6667
If the quotient is a whole number, then 3 and 116,720,071.6667 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 | 350,160,215 | |
| -1 | -350,160,215 |
Let's try dividing by 4:
350,160,215 ÷ 4 = 87,540,053.75
If the quotient is a whole number, then 4 and 87,540,053.75 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 | 350,160,215 | |
| -1 | 350,160,215 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 95 | 941 | 3,917 | 4,705 | 17,879 | 19,585 | 74,423 | 89,395 | 372,115 | 3,685,897 | 18,429,485 | 70,032,043 | 350,160,215 |
| -1 | -5 | -19 | -95 | -941 | -3,917 | -4,705 | -17,879 | -19,585 | -74,423 | -89,395 | -372,115 | -3,685,897 | -18,429,485 | -70,032,043 | -350,160,215 |
