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 355,043,317, 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 | 355,043,317 | |
| -1 | -355,043,317 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 355,043,317.
Example:
1 x 355,043,317 = 355,043,317
and
-1 x -355,043,317 = 355,043,317
Notice both answers equal 355,043,317
With that explanation out of the way, let's continue. Next, we take the number 355,043,317 and divide it by 2:
355,043,317 ÷ 2 = 177,521,658.5
If the quotient is a whole number, then 2 and 177,521,658.5 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 | 355,043,317 | |
| -1 | -355,043,317 |
Now, we try dividing 355,043,317 by 3:
355,043,317 ÷ 3 = 118,347,772.3333
If the quotient is a whole number, then 3 and 118,347,772.3333 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 | 355,043,317 | |
| -1 | -355,043,317 |
Let's try dividing by 4:
355,043,317 ÷ 4 = 88,760,829.25
If the quotient is a whole number, then 4 and 88,760,829.25 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 | 355,043,317 | |
| -1 | 355,043,317 |
If you did it right, you will end up with this table:
| 1 | 17 | 29 | 337 | 493 | 2,137 | 5,729 | 9,773 | 36,329 | 61,973 | 166,141 | 720,169 | 1,053,541 | 12,242,873 | 20,884,901 | 355,043,317 |
| -1 | -17 | -29 | -337 | -493 | -2,137 | -5,729 | -9,773 | -36,329 | -61,973 | -166,141 | -720,169 | -1,053,541 | -12,242,873 | -20,884,901 | -355,043,317 |
