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 335,423,645, 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 | 335,423,645 | |
| -1 | -335,423,645 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 335,423,645.
Example:
1 x 335,423,645 = 335,423,645
and
-1 x -335,423,645 = 335,423,645
Notice both answers equal 335,423,645
With that explanation out of the way, let's continue. Next, we take the number 335,423,645 and divide it by 2:
335,423,645 ÷ 2 = 167,711,822.5
If the quotient is a whole number, then 2 and 167,711,822.5 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 | 335,423,645 | |
| -1 | -335,423,645 |
Now, we try dividing 335,423,645 by 3:
335,423,645 ÷ 3 = 111,807,881.6667
If the quotient is a whole number, then 3 and 111,807,881.6667 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 | 335,423,645 | |
| -1 | -335,423,645 |
Let's try dividing by 4:
335,423,645 ÷ 4 = 83,855,911.25
If the quotient is a whole number, then 4 and 83,855,911.25 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 | 335,423,645 | |
| -1 | 335,423,645 |
If you did it right, you will end up with this table:
| 1 | 5 | 89 | 173 | 445 | 865 | 4,357 | 15,397 | 21,785 | 76,985 | 387,773 | 753,761 | 1,938,865 | 3,768,805 | 67,084,729 | 335,423,645 |
| -1 | -5 | -89 | -173 | -445 | -865 | -4,357 | -15,397 | -21,785 | -76,985 | -387,773 | -753,761 | -1,938,865 | -3,768,805 | -67,084,729 | -335,423,645 |
