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 123,103,033, 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 | 123,103,033 | |
| -1 | -123,103,033 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 123,103,033.
Example:
1 x 123,103,033 = 123,103,033
and
-1 x -123,103,033 = 123,103,033
Notice both answers equal 123,103,033
With that explanation out of the way, let's continue. Next, we take the number 123,103,033 and divide it by 2:
123,103,033 ÷ 2 = 61,551,516.5
If the quotient is a whole number, then 2 and 61,551,516.5 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 | 123,103,033 | |
| -1 | -123,103,033 |
Now, we try dividing 123,103,033 by 3:
123,103,033 ÷ 3 = 41,034,344.3333
If the quotient is a whole number, then 3 and 41,034,344.3333 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 | 123,103,033 | |
| -1 | -123,103,033 |
Let's try dividing by 4:
123,103,033 ÷ 4 = 30,775,758.25
If the quotient is a whole number, then 4 and 30,775,758.25 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 | 123,103,033 | |
| -1 | 123,103,033 |
If you did it right, you will end up with this table:
| 1 | 19 | 37 | 41 | 703 | 779 | 1,517 | 4,271 | 28,823 | 81,149 | 158,027 | 175,111 | 3,002,513 | 3,327,109 | 6,479,107 | 123,103,033 |
| -1 | -19 | -37 | -41 | -703 | -779 | -1,517 | -4,271 | -28,823 | -81,149 | -158,027 | -175,111 | -3,002,513 | -3,327,109 | -6,479,107 | -123,103,033 |
