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 162,371,165, 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 | 162,371,165 | |
| -1 | -162,371,165 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 162,371,165.
Example:
1 x 162,371,165 = 162,371,165
and
-1 x -162,371,165 = 162,371,165
Notice both answers equal 162,371,165
With that explanation out of the way, let's continue. Next, we take the number 162,371,165 and divide it by 2:
162,371,165 ÷ 2 = 81,185,582.5
If the quotient is a whole number, then 2 and 81,185,582.5 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 | 162,371,165 | |
| -1 | -162,371,165 |
Now, we try dividing 162,371,165 by 3:
162,371,165 ÷ 3 = 54,123,721.6667
If the quotient is a whole number, then 3 and 54,123,721.6667 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 | 162,371,165 | |
| -1 | -162,371,165 |
Let's try dividing by 4:
162,371,165 ÷ 4 = 40,592,791.25
If the quotient is a whole number, then 4 and 40,592,791.25 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 | 162,371,165 | |
| -1 | 162,371,165 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 17 | 55 | 85 | 187 | 935 | 173,659 | 868,295 | 1,910,249 | 2,952,203 | 9,551,245 | 14,761,015 | 32,474,233 | 162,371,165 |
| -1 | -5 | -11 | -17 | -55 | -85 | -187 | -935 | -173,659 | -868,295 | -1,910,249 | -2,952,203 | -9,551,245 | -14,761,015 | -32,474,233 | -162,371,165 |
