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 246,062,165, 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 | 246,062,165 | |
| -1 | -246,062,165 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 246,062,165.
Example:
1 x 246,062,165 = 246,062,165
and
-1 x -246,062,165 = 246,062,165
Notice both answers equal 246,062,165
With that explanation out of the way, let's continue. Next, we take the number 246,062,165 and divide it by 2:
246,062,165 ÷ 2 = 123,031,082.5
If the quotient is a whole number, then 2 and 123,031,082.5 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 | 246,062,165 | |
| -1 | -246,062,165 |
Now, we try dividing 246,062,165 by 3:
246,062,165 ÷ 3 = 82,020,721.6667
If the quotient is a whole number, then 3 and 82,020,721.6667 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 | 246,062,165 | |
| -1 | -246,062,165 |
Let's try dividing by 4:
246,062,165 ÷ 4 = 61,515,541.25
If the quotient is a whole number, then 4 and 61,515,541.25 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 | 246,062,165 | |
| -1 | 246,062,165 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 23 | 85 | 115 | 391 | 1,955 | 125,863 | 629,315 | 2,139,671 | 2,894,849 | 10,698,355 | 14,474,245 | 49,212,433 | 246,062,165 |
| -1 | -5 | -17 | -23 | -85 | -115 | -391 | -1,955 | -125,863 | -629,315 | -2,139,671 | -2,894,849 | -10,698,355 | -14,474,245 | -49,212,433 | -246,062,165 |
