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 163,244,207, 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 | 163,244,207 | |
| -1 | -163,244,207 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 163,244,207.
Example:
1 x 163,244,207 = 163,244,207
and
-1 x -163,244,207 = 163,244,207
Notice both answers equal 163,244,207
With that explanation out of the way, let's continue. Next, we take the number 163,244,207 and divide it by 2:
163,244,207 ÷ 2 = 81,622,103.5
If the quotient is a whole number, then 2 and 81,622,103.5 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 | 163,244,207 | |
| -1 | -163,244,207 |
Now, we try dividing 163,244,207 by 3:
163,244,207 ÷ 3 = 54,414,735.6667
If the quotient is a whole number, then 3 and 54,414,735.6667 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 | 163,244,207 | |
| -1 | -163,244,207 |
Let's try dividing by 4:
163,244,207 ÷ 4 = 40,811,051.75
If the quotient is a whole number, then 4 and 40,811,051.75 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 | 163,244,207 | |
| -1 | 163,244,207 |
If you did it right, you will end up with this table:
| 1 | 7 | 47 | 113 | 329 | 791 | 4,391 | 5,311 | 30,737 | 37,177 | 206,377 | 496,183 | 1,444,639 | 3,473,281 | 23,320,601 | 163,244,207 |
| -1 | -7 | -47 | -113 | -329 | -791 | -4,391 | -5,311 | -30,737 | -37,177 | -206,377 | -496,183 | -1,444,639 | -3,473,281 | -23,320,601 | -163,244,207 |
