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 323,166,155, 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 | 323,166,155 | |
| -1 | -323,166,155 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 323,166,155.
Example:
1 x 323,166,155 = 323,166,155
and
-1 x -323,166,155 = 323,166,155
Notice both answers equal 323,166,155
With that explanation out of the way, let's continue. Next, we take the number 323,166,155 and divide it by 2:
323,166,155 ÷ 2 = 161,583,077.5
If the quotient is a whole number, then 2 and 161,583,077.5 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 | 323,166,155 | |
| -1 | -323,166,155 |
Now, we try dividing 323,166,155 by 3:
323,166,155 ÷ 3 = 107,722,051.6667
If the quotient is a whole number, then 3 and 107,722,051.6667 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 | 323,166,155 | |
| -1 | -323,166,155 |
Let's try dividing by 4:
323,166,155 ÷ 4 = 80,791,538.75
If the quotient is a whole number, then 4 and 80,791,538.75 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 | 323,166,155 | |
| -1 | 323,166,155 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 19 | 65 | 95 | 247 | 1,235 | 261,673 | 1,308,365 | 3,401,749 | 4,971,787 | 17,008,745 | 24,858,935 | 64,633,231 | 323,166,155 |
| -1 | -5 | -13 | -19 | -65 | -95 | -247 | -1,235 | -261,673 | -1,308,365 | -3,401,749 | -4,971,787 | -17,008,745 | -24,858,935 | -64,633,231 | -323,166,155 |
