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 335,126,813, 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 | 335,126,813 | |
| -1 | -335,126,813 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 335,126,813.
Example:
1 x 335,126,813 = 335,126,813
and
-1 x -335,126,813 = 335,126,813
Notice both answers equal 335,126,813
With that explanation out of the way, let's continue. Next, we take the number 335,126,813 and divide it by 2:
335,126,813 ÷ 2 = 167,563,406.5
If the quotient is a whole number, then 2 and 167,563,406.5 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 | 335,126,813 | |
| -1 | -335,126,813 |
Now, we try dividing 335,126,813 by 3:
335,126,813 ÷ 3 = 111,708,937.6667
If the quotient is a whole number, then 3 and 111,708,937.6667 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 | 335,126,813 | |
| -1 | -335,126,813 |
Let's try dividing by 4:
335,126,813 ÷ 4 = 83,781,703.25
If the quotient is a whole number, then 4 and 83,781,703.25 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 | 335,126,813 | |
| -1 | 335,126,813 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 29 | 161 | 203 | 667 | 4,669 | 71,777 | 502,439 | 1,650,871 | 2,081,533 | 11,556,097 | 14,570,731 | 47,875,259 | 335,126,813 |
| -1 | -7 | -23 | -29 | -161 | -203 | -667 | -4,669 | -71,777 | -502,439 | -1,650,871 | -2,081,533 | -11,556,097 | -14,570,731 | -47,875,259 | -335,126,813 |
