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 163,302,223, 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 | 163,302,223 | |
| -1 | -163,302,223 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 163,302,223.
Example:
1 x 163,302,223 = 163,302,223
and
-1 x -163,302,223 = 163,302,223
Notice both answers equal 163,302,223
With that explanation out of the way, let's continue. Next, we take the number 163,302,223 and divide it by 2:
163,302,223 ÷ 2 = 81,651,111.5
If the quotient is a whole number, then 2 and 81,651,111.5 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 | 163,302,223 | |
| -1 | -163,302,223 |
Now, we try dividing 163,302,223 by 3:
163,302,223 ÷ 3 = 54,434,074.3333
If the quotient is a whole number, then 3 and 54,434,074.3333 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 | 163,302,223 | |
| -1 | -163,302,223 |
Let's try dividing by 4:
163,302,223 ÷ 4 = 40,825,555.75
If the quotient is a whole number, then 4 and 40,825,555.75 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 | 163,302,223 | |
| -1 | 163,302,223 |
If you did it right, you will end up with this table:
| 1 | 7 | 107 | 263 | 749 | 829 | 1,841 | 5,803 | 28,141 | 88,703 | 196,987 | 218,027 | 620,921 | 1,526,189 | 23,328,889 | 163,302,223 |
| -1 | -7 | -107 | -263 | -749 | -829 | -1,841 | -5,803 | -28,141 | -88,703 | -196,987 | -218,027 | -620,921 | -1,526,189 | -23,328,889 | -163,302,223 |
