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 333,164,155, 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 | 333,164,155 | |
| -1 | -333,164,155 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 333,164,155.
Example:
1 x 333,164,155 = 333,164,155
and
-1 x -333,164,155 = 333,164,155
Notice both answers equal 333,164,155
With that explanation out of the way, let's continue. Next, we take the number 333,164,155 and divide it by 2:
333,164,155 ÷ 2 = 166,582,077.5
If the quotient is a whole number, then 2 and 166,582,077.5 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 | 333,164,155 | |
| -1 | -333,164,155 |
Now, we try dividing 333,164,155 by 3:
333,164,155 ÷ 3 = 111,054,718.3333
If the quotient is a whole number, then 3 and 111,054,718.3333 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 | 333,164,155 | |
| -1 | -333,164,155 |
Let's try dividing by 4:
333,164,155 ÷ 4 = 83,291,038.75
If the quotient is a whole number, then 4 and 83,291,038.75 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 | 333,164,155 | |
| -1 | 333,164,155 |
If you did it right, you will end up with this table:
| 1 | 5 | 41 | 101 | 205 | 505 | 4,141 | 16,091 | 20,705 | 80,455 | 659,731 | 1,625,191 | 3,298,655 | 8,125,955 | 66,632,831 | 333,164,155 |
| -1 | -5 | -41 | -101 | -205 | -505 | -4,141 | -16,091 | -20,705 | -80,455 | -659,731 | -1,625,191 | -3,298,655 | -8,125,955 | -66,632,831 | -333,164,155 |
