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 163,243,259, 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 | 163,243,259 | |
| -1 | -163,243,259 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 163,243,259.
Example:
1 x 163,243,259 = 163,243,259
and
-1 x -163,243,259 = 163,243,259
Notice both answers equal 163,243,259
With that explanation out of the way, let's continue. Next, we take the number 163,243,259 and divide it by 2:
163,243,259 ÷ 2 = 81,621,629.5
If the quotient is a whole number, then 2 and 81,621,629.5 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 | 163,243,259 | |
| -1 | -163,243,259 |
Now, we try dividing 163,243,259 by 3:
163,243,259 ÷ 3 = 54,414,419.6667
If the quotient is a whole number, then 3 and 54,414,419.6667 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 | 163,243,259 | |
| -1 | -163,243,259 |
Let's try dividing by 4:
163,243,259 ÷ 4 = 40,810,814.75
If the quotient is a whole number, then 4 and 40,810,814.75 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 | 163,243,259 | |
| -1 | 163,243,259 |
If you did it right, you will end up with this table:
| 1 | 23 | 61 | 307 | 379 | 1,403 | 7,061 | 8,717 | 18,727 | 23,119 | 116,353 | 430,721 | 531,737 | 2,676,119 | 7,097,533 | 163,243,259 |
| -1 | -23 | -61 | -307 | -379 | -1,403 | -7,061 | -8,717 | -18,727 | -23,119 | -116,353 | -430,721 | -531,737 | -2,676,119 | -7,097,533 | -163,243,259 |
