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 30,233,203, 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 | 30,233,203 | |
| -1 | -30,233,203 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 30,233,203.
Example:
1 x 30,233,203 = 30,233,203
and
-1 x -30,233,203 = 30,233,203
Notice both answers equal 30,233,203
With that explanation out of the way, let's continue. Next, we take the number 30,233,203 and divide it by 2:
30,233,203 ÷ 2 = 15,116,601.5
If the quotient is a whole number, then 2 and 15,116,601.5 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 | 30,233,203 | |
| -1 | -30,233,203 |
Now, we try dividing 30,233,203 by 3:
30,233,203 ÷ 3 = 10,077,734.3333
If the quotient is a whole number, then 3 and 10,077,734.3333 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 | 30,233,203 | |
| -1 | -30,233,203 |
Let's try dividing by 4:
30,233,203 ÷ 4 = 7,558,300.75
If the quotient is a whole number, then 4 and 7,558,300.75 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 | 30,233,203 | |
| -1 | 30,233,203 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 13 | 77 | 91 | 143 | 1,001 | 30,203 | 211,421 | 332,233 | 392,639 | 2,325,631 | 2,748,473 | 4,319,029 | 30,233,203 |
| -1 | -7 | -11 | -13 | -77 | -91 | -143 | -1,001 | -30,203 | -211,421 | -332,233 | -392,639 | -2,325,631 | -2,748,473 | -4,319,029 | -30,233,203 |
