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 103,423,433, 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 | 103,423,433 | |
| -1 | -103,423,433 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 103,423,433.
Example:
1 x 103,423,433 = 103,423,433
and
-1 x -103,423,433 = 103,423,433
Notice both answers equal 103,423,433
With that explanation out of the way, let's continue. Next, we take the number 103,423,433 and divide it by 2:
103,423,433 ÷ 2 = 51,711,716.5
If the quotient is a whole number, then 2 and 51,711,716.5 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 | 103,423,433 | |
| -1 | -103,423,433 |
Now, we try dividing 103,423,433 by 3:
103,423,433 ÷ 3 = 34,474,477.6667
If the quotient is a whole number, then 3 and 34,474,477.6667 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 | 103,423,433 | |
| -1 | -103,423,433 |
Let's try dividing by 4:
103,423,433 ÷ 4 = 25,855,858.25
If the quotient is a whole number, then 4 and 25,855,858.25 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 | 103,423,433 | |
| -1 | 103,423,433 |
If you did it right, you will end up with this table:
| 1 | 23 | 103 | 149 | 293 | 2,369 | 3,427 | 6,739 | 15,347 | 30,179 | 43,657 | 352,981 | 694,117 | 1,004,111 | 4,496,671 | 103,423,433 |
| -1 | -23 | -103 | -149 | -293 | -2,369 | -3,427 | -6,739 | -15,347 | -30,179 | -43,657 | -352,981 | -694,117 | -1,004,111 | -4,496,671 | -103,423,433 |
