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 355,005,305, 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 | 355,005,305 | |
| -1 | -355,005,305 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 355,005,305.
Example:
1 x 355,005,305 = 355,005,305
and
-1 x -355,005,305 = 355,005,305
Notice both answers equal 355,005,305
With that explanation out of the way, let's continue. Next, we take the number 355,005,305 and divide it by 2:
355,005,305 ÷ 2 = 177,502,652.5
If the quotient is a whole number, then 2 and 177,502,652.5 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 | 355,005,305 | |
| -1 | -355,005,305 |
Now, we try dividing 355,005,305 by 3:
355,005,305 ÷ 3 = 118,335,101.6667
If the quotient is a whole number, then 3 and 118,335,101.6667 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 | 355,005,305 | |
| -1 | -355,005,305 |
Let's try dividing by 4:
355,005,305 ÷ 4 = 88,751,326.25
If the quotient is a whole number, then 4 and 88,751,326.25 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 | 355,005,305 | |
| -1 | 355,005,305 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 139 | 695 | 2,363 | 11,815 | 30,047 | 150,235 | 510,799 | 2,553,995 | 4,176,533 | 20,882,665 | 71,001,061 | 355,005,305 |
| -1 | -5 | -17 | -85 | -139 | -695 | -2,363 | -11,815 | -30,047 | -150,235 | -510,799 | -2,553,995 | -4,176,533 | -20,882,665 | -71,001,061 | -355,005,305 |
