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 433,342,021, 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 | 433,342,021 | |
| -1 | -433,342,021 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 433,342,021.
Example:
1 x 433,342,021 = 433,342,021
and
-1 x -433,342,021 = 433,342,021
Notice both answers equal 433,342,021
With that explanation out of the way, let's continue. Next, we take the number 433,342,021 and divide it by 2:
433,342,021 ÷ 2 = 216,671,010.5
If the quotient is a whole number, then 2 and 216,671,010.5 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 | 433,342,021 | |
| -1 | -433,342,021 |
Now, we try dividing 433,342,021 by 3:
433,342,021 ÷ 3 = 144,447,340.3333
If the quotient is a whole number, then 3 and 144,447,340.3333 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 | 433,342,021 | |
| -1 | -433,342,021 |
Let's try dividing by 4:
433,342,021 ÷ 4 = 108,335,505.25
If the quotient is a whole number, then 4 and 108,335,505.25 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 | 433,342,021 | |
| -1 | 433,342,021 |
If you did it right, you will end up with this table:
| 1 | 7 | 47 | 233 | 329 | 1,631 | 5,653 | 10,951 | 39,571 | 76,657 | 265,691 | 1,317,149 | 1,859,837 | 9,220,043 | 61,906,003 | 433,342,021 |
| -1 | -7 | -47 | -233 | -329 | -1,631 | -5,653 | -10,951 | -39,571 | -76,657 | -265,691 | -1,317,149 | -1,859,837 | -9,220,043 | -61,906,003 | -433,342,021 |
