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 335,531,315, 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 | 335,531,315 | |
| -1 | -335,531,315 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 335,531,315.
Example:
1 x 335,531,315 = 335,531,315
and
-1 x -335,531,315 = 335,531,315
Notice both answers equal 335,531,315
With that explanation out of the way, let's continue. Next, we take the number 335,531,315 and divide it by 2:
335,531,315 ÷ 2 = 167,765,657.5
If the quotient is a whole number, then 2 and 167,765,657.5 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 | 335,531,315 | |
| -1 | -335,531,315 |
Now, we try dividing 335,531,315 by 3:
335,531,315 ÷ 3 = 111,843,771.6667
If the quotient is a whole number, then 3 and 111,843,771.6667 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 | 335,531,315 | |
| -1 | -335,531,315 |
Let's try dividing by 4:
335,531,315 ÷ 4 = 83,882,828.75
If the quotient is a whole number, then 4 and 83,882,828.75 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 | 335,531,315 | |
| -1 | 335,531,315 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 1,163 | 5,815 | 8,141 | 8,243 | 40,705 | 41,215 | 57,701 | 288,505 | 9,586,609 | 47,933,045 | 67,106,263 | 335,531,315 |
| -1 | -5 | -7 | -35 | -1,163 | -5,815 | -8,141 | -8,243 | -40,705 | -41,215 | -57,701 | -288,505 | -9,586,609 | -47,933,045 | -67,106,263 | -335,531,315 |
