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 355,050,161, 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 | 355,050,161 | |
| -1 | -355,050,161 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 355,050,161.
Example:
1 x 355,050,161 = 355,050,161
and
-1 x -355,050,161 = 355,050,161
Notice both answers equal 355,050,161
With that explanation out of the way, let's continue. Next, we take the number 355,050,161 and divide it by 2:
355,050,161 ÷ 2 = 177,525,080.5
If the quotient is a whole number, then 2 and 177,525,080.5 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 | 355,050,161 | |
| -1 | -355,050,161 |
Now, we try dividing 355,050,161 by 3:
355,050,161 ÷ 3 = 118,350,053.6667
If the quotient is a whole number, then 3 and 118,350,053.6667 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 | 355,050,161 | |
| -1 | -355,050,161 |
Let's try dividing by 4:
355,050,161 ÷ 4 = 88,762,540.25
If the quotient is a whole number, then 4 and 88,762,540.25 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 | 355,050,161 | |
| -1 | 355,050,161 |
If you did it right, you will end up with this table:
| 1 | 29 | 31 | 463 | 853 | 899 | 13,427 | 14,353 | 24,737 | 26,443 | 394,939 | 416,237 | 766,847 | 11,453,231 | 12,243,109 | 355,050,161 |
| -1 | -29 | -31 | -463 | -853 | -899 | -13,427 | -14,353 | -24,737 | -26,443 | -394,939 | -416,237 | -766,847 | -11,453,231 | -12,243,109 | -355,050,161 |
