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 123,013,033, 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 | 123,013,033 | |
| -1 | -123,013,033 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 123,013,033.
Example:
1 x 123,013,033 = 123,013,033
and
-1 x -123,013,033 = 123,013,033
Notice both answers equal 123,013,033
With that explanation out of the way, let's continue. Next, we take the number 123,013,033 and divide it by 2:
123,013,033 ÷ 2 = 61,506,516.5
If the quotient is a whole number, then 2 and 61,506,516.5 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 | 123,013,033 | |
| -1 | -123,013,033 |
Now, we try dividing 123,013,033 by 3:
123,013,033 ÷ 3 = 41,004,344.3333
If the quotient is a whole number, then 3 and 41,004,344.3333 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 | 123,013,033 | |
| -1 | -123,013,033 |
Let's try dividing by 4:
123,013,033 ÷ 4 = 30,753,258.25
If the quotient is a whole number, then 4 and 30,753,258.25 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 | 123,013,033 | |
| -1 | 123,013,033 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 79 | 143 | 869 | 1,027 | 10,889 | 11,297 | 119,779 | 141,557 | 860,231 | 1,557,127 | 9,462,541 | 11,183,003 | 123,013,033 |
| -1 | -11 | -13 | -79 | -143 | -869 | -1,027 | -10,889 | -11,297 | -119,779 | -141,557 | -860,231 | -1,557,127 | -9,462,541 | -11,183,003 | -123,013,033 |
