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 42,243,433, 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 | 42,243,433 | |
| -1 | -42,243,433 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 42,243,433.
Example:
1 x 42,243,433 = 42,243,433
and
-1 x -42,243,433 = 42,243,433
Notice both answers equal 42,243,433
With that explanation out of the way, let's continue. Next, we take the number 42,243,433 and divide it by 2:
42,243,433 ÷ 2 = 21,121,716.5
If the quotient is a whole number, then 2 and 21,121,716.5 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 | 42,243,433 | |
| -1 | -42,243,433 |
Now, we try dividing 42,243,433 by 3:
42,243,433 ÷ 3 = 14,081,144.3333
If the quotient is a whole number, then 3 and 14,081,144.3333 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 | 42,243,433 | |
| -1 | -42,243,433 |
Let's try dividing by 4:
42,243,433 ÷ 4 = 10,560,858.25
If the quotient is a whole number, then 4 and 10,560,858.25 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 | 42,243,433 | |
| -1 | 42,243,433 |
If you did it right, you will end up with this table:
| 1 | 23 | 67 | 79 | 347 | 1,541 | 1,817 | 5,293 | 7,981 | 23,249 | 27,413 | 121,739 | 534,727 | 630,499 | 1,836,671 | 42,243,433 |
| -1 | -23 | -67 | -79 | -347 | -1,541 | -1,817 | -5,293 | -7,981 | -23,249 | -27,413 | -121,739 | -534,727 | -630,499 | -1,836,671 | -42,243,433 |
