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 355,066,355, 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 | 355,066,355 | |
| -1 | -355,066,355 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 355,066,355.
Example:
1 x 355,066,355 = 355,066,355
and
-1 x -355,066,355 = 355,066,355
Notice both answers equal 355,066,355
With that explanation out of the way, let's continue. Next, we take the number 355,066,355 and divide it by 2:
355,066,355 ÷ 2 = 177,533,177.5
If the quotient is a whole number, then 2 and 177,533,177.5 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 | 355,066,355 | |
| -1 | -355,066,355 |
Now, we try dividing 355,066,355 by 3:
355,066,355 ÷ 3 = 118,355,451.6667
If the quotient is a whole number, then 3 and 118,355,451.6667 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 | 355,066,355 | |
| -1 | -355,066,355 |
Let's try dividing by 4:
355,066,355 ÷ 4 = 88,766,588.75
If the quotient is a whole number, then 4 and 88,766,588.75 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 | 355,066,355 | |
| -1 | 355,066,355 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 41 | 205 | 287 | 1,435 | 247,433 | 1,237,165 | 1,732,031 | 8,660,155 | 10,144,753 | 50,723,765 | 71,013,271 | 355,066,355 |
| -1 | -5 | -7 | -35 | -41 | -205 | -287 | -1,435 | -247,433 | -1,237,165 | -1,732,031 | -8,660,155 | -10,144,753 | -50,723,765 | -71,013,271 | -355,066,355 |
