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 353,205,055, 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 | 353,205,055 | |
| -1 | -353,205,055 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 353,205,055.
Example:
1 x 353,205,055 = 353,205,055
and
-1 x -353,205,055 = 353,205,055
Notice both answers equal 353,205,055
With that explanation out of the way, let's continue. Next, we take the number 353,205,055 and divide it by 2:
353,205,055 ÷ 2 = 176,602,527.5
If the quotient is a whole number, then 2 and 176,602,527.5 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 | 353,205,055 | |
| -1 | -353,205,055 |
Now, we try dividing 353,205,055 by 3:
353,205,055 ÷ 3 = 117,735,018.3333
If the quotient is a whole number, then 3 and 117,735,018.3333 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 | 353,205,055 | |
| -1 | -353,205,055 |
Let's try dividing by 4:
353,205,055 ÷ 4 = 88,301,263.75
If the quotient is a whole number, then 4 and 88,301,263.75 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 | 353,205,055 | |
| -1 | 353,205,055 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 263 | 1,315 | 1,841 | 9,205 | 38,371 | 191,855 | 268,597 | 1,342,985 | 10,091,573 | 50,457,865 | 70,641,011 | 353,205,055 |
| -1 | -5 | -7 | -35 | -263 | -1,315 | -1,841 | -9,205 | -38,371 | -191,855 | -268,597 | -1,342,985 | -10,091,573 | -50,457,865 | -70,641,011 | -353,205,055 |
