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 335,115,155, 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 | 335,115,155 | |
| -1 | -335,115,155 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 335,115,155.
Example:
1 x 335,115,155 = 335,115,155
and
-1 x -335,115,155 = 335,115,155
Notice both answers equal 335,115,155
With that explanation out of the way, let's continue. Next, we take the number 335,115,155 and divide it by 2:
335,115,155 ÷ 2 = 167,557,577.5
If the quotient is a whole number, then 2 and 167,557,577.5 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 | 335,115,155 | |
| -1 | -335,115,155 |
Now, we try dividing 335,115,155 by 3:
335,115,155 ÷ 3 = 111,705,051.6667
If the quotient is a whole number, then 3 and 111,705,051.6667 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 | 335,115,155 | |
| -1 | -335,115,155 |
Let's try dividing by 4:
335,115,155 ÷ 4 = 83,778,788.75
If the quotient is a whole number, then 4 and 83,778,788.75 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 | 335,115,155 | |
| -1 | 335,115,155 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 145 | 149 | 745 | 4,321 | 15,511 | 21,605 | 77,555 | 449,819 | 2,249,095 | 2,311,139 | 11,555,695 | 67,023,031 | 335,115,155 |
| -1 | -5 | -29 | -145 | -149 | -745 | -4,321 | -15,511 | -21,605 | -77,555 | -449,819 | -2,249,095 | -2,311,139 | -11,555,695 | -67,023,031 | -335,115,155 |
