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 42,433,433, 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 | 42,433,433 | |
| -1 | -42,433,433 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 42,433,433.
Example:
1 x 42,433,433 = 42,433,433
and
-1 x -42,433,433 = 42,433,433
Notice both answers equal 42,433,433
With that explanation out of the way, let's continue. Next, we take the number 42,433,433 and divide it by 2:
42,433,433 ÷ 2 = 21,216,716.5
If the quotient is a whole number, then 2 and 21,216,716.5 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 | 42,433,433 | |
| -1 | -42,433,433 |
Now, we try dividing 42,433,433 by 3:
42,433,433 ÷ 3 = 14,144,477.6667
If the quotient is a whole number, then 3 and 14,144,477.6667 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 | 42,433,433 | |
| -1 | -42,433,433 |
Let's try dividing by 4:
42,433,433 ÷ 4 = 10,608,358.25
If the quotient is a whole number, then 4 and 10,608,358.25 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 | 42,433,433 | |
| -1 | 42,433,433 |
If you did it right, you will end up with this table:
| 1 | 7 | 47 | 101 | 329 | 707 | 1,277 | 4,747 | 8,939 | 33,229 | 60,019 | 128,977 | 420,133 | 902,839 | 6,061,919 | 42,433,433 |
| -1 | -7 | -47 | -101 | -329 | -707 | -1,277 | -4,747 | -8,939 | -33,229 | -60,019 | -128,977 | -420,133 | -902,839 | -6,061,919 | -42,433,433 |
