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 103,123,033, 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 | 103,123,033 | |
| -1 | -103,123,033 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 103,123,033.
Example:
1 x 103,123,033 = 103,123,033
and
-1 x -103,123,033 = 103,123,033
Notice both answers equal 103,123,033
With that explanation out of the way, let's continue. Next, we take the number 103,123,033 and divide it by 2:
103,123,033 ÷ 2 = 51,561,516.5
If the quotient is a whole number, then 2 and 51,561,516.5 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 | 103,123,033 | |
| -1 | -103,123,033 |
Now, we try dividing 103,123,033 by 3:
103,123,033 ÷ 3 = 34,374,344.3333
If the quotient is a whole number, then 3 and 34,374,344.3333 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 | 103,123,033 | |
| -1 | -103,123,033 |
Let's try dividing by 4:
103,123,033 ÷ 4 = 25,780,758.25
If the quotient is a whole number, then 4 and 25,780,758.25 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 | 103,123,033 | |
| -1 | 103,123,033 |
If you did it right, you will end up with this table:
| 1 | 13 | 37 | 269 | 481 | 797 | 3,497 | 9,953 | 10,361 | 29,489 | 129,389 | 214,393 | 383,357 | 2,787,109 | 7,932,541 | 103,123,033 |
| -1 | -13 | -37 | -269 | -481 | -797 | -3,497 | -9,953 | -10,361 | -29,489 | -129,389 | -214,393 | -383,357 | -2,787,109 | -7,932,541 | -103,123,033 |
