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 335,402,215, 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 | 335,402,215 | |
| -1 | -335,402,215 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 335,402,215.
Example:
1 x 335,402,215 = 335,402,215
and
-1 x -335,402,215 = 335,402,215
Notice both answers equal 335,402,215
With that explanation out of the way, let's continue. Next, we take the number 335,402,215 and divide it by 2:
335,402,215 ÷ 2 = 167,701,107.5
If the quotient is a whole number, then 2 and 167,701,107.5 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 | 335,402,215 | |
| -1 | -335,402,215 |
Now, we try dividing 335,402,215 by 3:
335,402,215 ÷ 3 = 111,800,738.3333
If the quotient is a whole number, then 3 and 111,800,738.3333 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 | 335,402,215 | |
| -1 | -335,402,215 |
Let's try dividing by 4:
335,402,215 ÷ 4 = 83,850,553.75
If the quotient is a whole number, then 4 and 83,850,553.75 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 | 335,402,215 | |
| -1 | 335,402,215 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 115 | 1,459 | 1,999 | 7,295 | 9,995 | 33,557 | 45,977 | 167,785 | 229,885 | 2,916,541 | 14,582,705 | 67,080,443 | 335,402,215 |
| -1 | -5 | -23 | -115 | -1,459 | -1,999 | -7,295 | -9,995 | -33,557 | -45,977 | -167,785 | -229,885 | -2,916,541 | -14,582,705 | -67,080,443 | -335,402,215 |
