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 335,510,071, 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 | 335,510,071 | |
| -1 | -335,510,071 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 335,510,071.
Example:
1 x 335,510,071 = 335,510,071
and
-1 x -335,510,071 = 335,510,071
Notice both answers equal 335,510,071
With that explanation out of the way, let's continue. Next, we take the number 335,510,071 and divide it by 2:
335,510,071 ÷ 2 = 167,755,035.5
If the quotient is a whole number, then 2 and 167,755,035.5 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 | 335,510,071 | |
| -1 | -335,510,071 |
Now, we try dividing 335,510,071 by 3:
335,510,071 ÷ 3 = 111,836,690.3333
If the quotient is a whole number, then 3 and 111,836,690.3333 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 | 335,510,071 | |
| -1 | -335,510,071 |
Let's try dividing by 4:
335,510,071 ÷ 4 = 83,877,517.75
If the quotient is a whole number, then 4 and 83,877,517.75 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 | 335,510,071 | |
| -1 | 335,510,071 |
If you did it right, you will end up with this table:
| 1 | 13 | 67 | 151 | 871 | 1,963 | 2,551 | 10,117 | 33,163 | 131,521 | 170,917 | 385,201 | 2,221,921 | 5,007,613 | 25,808,467 | 335,510,071 |
| -1 | -13 | -67 | -151 | -871 | -1,963 | -2,551 | -10,117 | -33,163 | -131,521 | -170,917 | -385,201 | -2,221,921 | -5,007,613 | -25,808,467 | -335,510,071 |
