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 353,510,135, 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 | 353,510,135 | |
| -1 | -353,510,135 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 353,510,135.
Example:
1 x 353,510,135 = 353,510,135
and
-1 x -353,510,135 = 353,510,135
Notice both answers equal 353,510,135
With that explanation out of the way, let's continue. Next, we take the number 353,510,135 and divide it by 2:
353,510,135 ÷ 2 = 176,755,067.5
If the quotient is a whole number, then 2 and 176,755,067.5 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 | 353,510,135 | |
| -1 | -353,510,135 |
Now, we try dividing 353,510,135 by 3:
353,510,135 ÷ 3 = 117,836,711.6667
If the quotient is a whole number, then 3 and 117,836,711.6667 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 | 353,510,135 | |
| -1 | -353,510,135 |
Let's try dividing by 4:
353,510,135 ÷ 4 = 88,377,533.75
If the quotient is a whole number, then 4 and 88,377,533.75 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 | 353,510,135 | |
| -1 | 353,510,135 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 263 | 1,315 | 2,893 | 14,465 | 24,439 | 122,195 | 268,829 | 1,344,145 | 6,427,457 | 32,137,285 | 70,702,027 | 353,510,135 |
| -1 | -5 | -11 | -55 | -263 | -1,315 | -2,893 | -14,465 | -24,439 | -122,195 | -268,829 | -1,344,145 | -6,427,457 | -32,137,285 | -70,702,027 | -353,510,135 |
